Algebra expression is directly related to the algebraic equations and polynomial equations. In the equation, you have one or more than one unknown, but the values cannot be determined when there is no equation including same unknown. The algebraic equations are most probably used to find the variables values to make both the side equal. For example, you have algebraic equation such as
4x + 8y = 18
And other one is, 3x+ 4y = 14,
Now, you have to find the value of x and y respectively. To find the values of unknown, you must know mathematical operations such as addition, subtraction, multiplication, and division.
To solve this algebra expression, apply subtraction operation on the both. In subtraction, only same variables can subtract. That means the 4x may subtract from 3x and similarly, 8y subtract from 4y. The constant value subtracts from a constant value of other equation.
Note that, before subtracting the equation, it needs to make the variables same. That means if we do not make the values same, then we have the equation in which both unknown are available. Then we can never find the value. To avoid this complexity in algebra expression, multiply the number with both the equation. It is not difficult to find the number to multiply in an equation. Find the unknown which you want to eliminate. Then select the number according to it. You want to eliminate x from both the equation then multiply equation one by 3, and another one is 4.
Now you have new equations as,
12x + 24y = 54
And, second one becomes, 12x + 16y = 56
Now you have the option to eliminate the variable x from the equation. For this, you need to subtract equation one from two. Then you have a new equation which has only one unknown because the second one has eliminated.
You have, 8y = -2,
Don’t you worry if you have answered in negative because in algebra expression; you have to face lots of questions that include negative value? It is easy to find the unknown if you have only one unknown. Divide both the side of an equation by 8, and you will get the value of y.
You have, y = -1/4
After getting the one variable’s value, you have to find another one. Now put Y’s value on anyone equation in which x is present. Consider equation one,
4x + 8y = 18,
When putting the value of y,
You have, 4x – 2 = 18
Not transfer the constant value to the right side. Then you have,
4x = 20,
Divide both the side by 4, and you have x = 5
In algebra expression, you need to face various difficulties which are solved by considering important factors. The application of algebraic equation helps to know the certain results. To solve the difficult expression, you need to practice more and more. More the practice takes you to be expert in solving the algebraic equations. The basic of algebra is simple but difficult to solve their application. Regular practicing can make you perfect in algebra expression-solving.
Mathematics is the subject that is tough, but interesting. Many people face a problem with many topics of the mathematics. If you found it difficult to solve the fraction to decimal problems, you should read the steps explained further to solve such problems. Firstly, you should know what is a decimal or fraction number. A decimal number is a number that has a decimal point, and it is a number of base-10 number system. For example 10.0, 0.45, 1.75 is the decimal numbers.
There are commonly three types of the fraction. It includes a proper fraction, improper fraction, and the mixed fraction. If the numerator is less than the denominator, then it is called as a proper fraction, for example, 5/8. On the other hand, if the numerator is greater than the denominator, then it is called as the improper fraction, for example, 4/3. Mixed fraction has a whole number as well as a fraction.
It is true that we are living in a modern world and we have the calculators in computers and mobile phones. Anyone can easily calculate the fraction form of a decimal number. But you should know the manual method of solving the fraction to decimal problems. You can easily solve such problems by following these easy steps.
The easy steps to convert a fraction to decimal number with an example
• Step 1: you must have to find a number that you can multiply by the number at the denominator place of the fraction. So, it can convert the number at denominator to 10, or 100, or 1000 and so on. We will take an example here as 5/4. So, you should find the right number that will make the denominator of this fraction that is 4 to 100 on multiplication. You can’t make it 10 as it is not a multiple of 4. So you have to find a number which you can multiply to 4 to make 100 at the denominator. You can multiply 25 by 4 so you can make it 100.
• Step 2: The next step is to multiply both the numerator and denominator by that number. In this example, you have to multiply 5 and 4 by 25 so you will get a result as 125/100. It is an important step to finding a correct answer of any fraction to the decimal problem. If you want a proper solution, you must multiply correctly.
• Step 3: the last step is just to right down the numerator number by correctly putting the decimal point in the right spot. In this example, you have to place a decimal point after two spaces from the right side due to the reason that there are two zeros in the denominator. So the correct decimal of the fraction 5/4 is 1.25.
Thus, these are the simple steps that are applicable for both the improper and proper fractions. The example given with these steps helps to get a good idea about it. If you practice some more problems of the fraction to a decimal by using these steps, your concept will be clear. You can then easily solve any problem on this topic.

Fractions vs. Decimals:
Decimal numbers are important because people use them in their day to day life in various situations, such as looking at temperature and humidity on a particular day, glancing at price tags while shopping, reading the digital blood pressure monitor or analyzing their favorite basket ball match. The decimal system is a way to express large and small numbers by utilizing the decimal point. But decimals are not quite handy in many real life situations. For instance, if you want to fabricate a bench, you might need to have it five feet three and a half inches long (5' 3 1/2"). Assuming that you cut the wooden board bit longer and your supervisor asks to cut off an eighth of an inch, being good at fractions in that situation would make it easier to comprehend the instructions. In making strong foundations for basic mathematics, we need to have strong walls. Algebra serves the purpose of those walls that keep the roof of mathematics lifted up. And if the math house is to have a sustainable roof in the future, it needs a really strong algebra. And for algebra to be strong you need to be good at fractions. Academically, almost all sorts of tests have a large portion of questions from the topic of fractions. Apart from academics, fractions and applying different arithmetic operations on them, are an essential part of our daily lives. Let it be dividing a cake pie or making up space by separating a large room, where ever be the need for division, without the skill of fractions things would get messed up.
To multiply two fractions, we multiply the numerators to get the new numerator and multiply the denominators to get the new denominator. Then the final step involves the simplification of a fraction, in case they are not in their lowest terms. When multiplying a fraction with a mixed number or multiplying two mixed fractions, the first step is to change the mixed fraction into an improper fraction. Then simplify the terms if possible, and the same process of multiplying the numerator by the other counterpart and denominator from the other one is performed. Finally, simplify and put the result in simplest terms if applicable.
The practical implication of multiplying fractions can be observed in the fields of construction, map scaling, surveying, salary payrolls, house hold jobs such as cooking, distance and volume calculations, family budget estimation, etc.
For instance, a family uses 1/3 of its monthly income for housing and utilities on average. If the family’s monthly income is $100, what is spent on housing and utilities? What amount remains? Evaluating the result would be really easy and fast if one is familiar with fractions. The family's income is $100. So as stated in the problem, it spends 1/3rd on housing and utilities. Therefore '$100 / 3' i.e. ~$33 are spent. The remaining amount can be calculated by subtracting the spent amount from total income. That comes out to be as $100 - $33. The remaining amount would be $67 on average. Hence the skill of multiplying fractions comes in as a handy tool in solving day to day mathematical problems quickly.
A Linear equation is a part of algebra in mathematics. In a linear equation, each term is a constant or it can be a product of constant of the variable. A very simple equation that can be written with one variable (x) could be ax + b=0, where a and b are constant and a ≠ 0. The constants a and b could be any numbers or parameters. Linear equations are universal in the applications of mathematics. Those equations that involve single variable will appear in simplest problems wherein one unknown parameter or quantity has to be solved from the other information which is given. In solving simple equations, one needs to use only elementary operations of arithmetic such as addition, multiplication, subtraction, and division.
How to solve linear equations?
One can solve the linear equations with visualization which is the ability or the process, and the product of the creation, use of, interpretation, and reflection which is used upon the pictures, diagrams, and images in the minds, paper or technological tools. The purpose of the solving is to depict and communicate the information which is thought upon and developed using previously unknown ideas and of advancing understandings.
Linear Equations with More Variables:
Equations can have one more one variables, such as equation with three variables x, y, and z is written asax + by + cz = 0, wherein a, b, and c are the constants and are any number except zero.
Equations with the exponents that are greater than one are known as non – linear equations. For example, axy + b = 0, where a and b are constants and a is not equal to zero. The equation has two variables x and y and is said to be non – linear as the sum of the exponents of the two variables in the first term is two.
Forms of Two – Dimensional Linear Equations
There are different forms in which the linear equations can be written. These are:

Keeping in mind the end goal to ace science, you certainly need to ace fractions. These shows up in each and every part of this teach, from variable based math to analytics to building to related fields like material science. Fractions exhibit a considerable measure of inconvenience to understudies, yet the greater part of these issues can be effectively settled if the correct approach is taken. Here in Part II, we look at some different procedures important to ace this zone.
The system of fractions is simply fractions that have a similar esteem. Consequently, 1/2, 2/4, and 3/6 are all equal fractions. Identical fraction has a similar esteem, however, have distinctive numerators and denominators from alternate fractions to which they are comparable. There are limitlessly numerous proportional fractions to 1/2, let us say. Each of these can be inferred by increasing 1/2 by 1 in the masked frame. What we mean by 1 in camouflaged shape is a fraction which has an indistinguishable numerator from the denominator. Accordingly 2/2, 3/3, 4/4... And so on are each of the 1 in camouflaged shape. Keep in mind: 1 is the multiplicative character, and in this way regardless of what we increase by 1 does not have its esteem changed.
The system of fractions comes in exceptionally convenient when we include or subtract fractions since this operation requires that we have a similar denominator. Accordingly if including 1/2 and 3/8, we have to change over the 1/2 into a comparable fraction with 8 as its denominator. We basically ask ourselves what we have to duplicate 2 by to get 8. The answer is simple and is 4. Subsequently, we utilize 4/4, 1 in camouflaged shape to increase and change over 1/2 into the identical fraction 4/8. We can then include 4/8 and 3/8 to get 7/8.
Another critical part of the system of fractions comes when they are multiplying and subtracting them. This is most likely one of the least demanding operations including fractions since we require not worry about shared factors. To increase two fractions, we just duplicate the numerators and after that the denominators. It ought to be brought up that we ought to first attempt to diminish the fractions so that our final product is in most minimal terms. Doing this, to begin with, additionally, rearranges the augmentations. For instance, (38/57)x(20/25) is less demanding to do in the event that we first diminish every fraction as said above to 2/3 and 4/5, separately. We then increase 2x4 and 3x5 to get 8/15 as our reply, and this is in most minimal terms. In the event that you don't disentangle, to begin with, you are taking a gander at increasing 38x20 and 57x25, which are harder duplications than the ones we.
Subtracting fraction is truly the same than duplicating them, with one exemption. Before we do the augmentation, we rearrange the numerator and denominator of the second fraction. We then basically increase. Hence (9/15)/(8/16) is the same as (9/15)x 16/8). How about we diminish and increase. We have (3/5)x(2/1) = 6/5.
Acing these methods will give you the edge in overcoming fraction. Utilize these articles and the strategies laid out in that to defeat any issues you may have had with these obstinate numerical elements. You will soon understand that fractions are very amusing to work with.
