Easy To Use Addition And Subtraction Worksheets For Practice

Fractions are often used in everyday life. The addition of fractions is the most frequently used arithmetic operation. Why is the addition so important? Because we usually add fractions in everyday life. For example, half a quintal of rice adds half a quintal of rice to one quintal; My salary is divided into three, one third for food, one third for operations, and one third for savings, and so on. All of them are the form of the addition of fractions.

How to Add Fractions

To add fractions, there is a method that must be followed, or it can be said as the formula for adding fractions, that is, you must first equalize all the denominators for the fraction to be added. For this reason, it is necessary to convert the fraction to another form but the value must be the same. For example, 1/2 has the same value as 2/4, 3/6, 15/30, 26/52, 200/400, 1000/2000, 1234/2468, and so on. Note that all of these numbers represent a value equal to 1/2.

Example of Addition of Fractions

To better understand how to add fractions, we will show you how to answer various fraction addition questions, both regular and mixed numbers.

Example Problem 1: Addition of Regular Fractions

Count: 1/3 + 1/3 = …?

Answer:

So 1/3 + 1/3 = 2/3.

PLEASE NOTE.

The colors of the denominator and numerator are made colorful so that it is easy to trace numbers when the fraction addition process is carried out. For example, in the fraction addition problem above you will see the number 1 in red and green and how the number moves when the addition is carried out.


Example Problem 2: Addition of Regular Fractions

Count: 1/2 + 1/3 = …?

Answer:

Why is there a multiplier of 3 on 1/2? Because it’s not actually times 3, but multiplied by 3/3 or more precisely times 1. Remember! 3/3 = 1. So it doesn’t change the value or you could say 1/2 = 3/6. Meanwhile, 1/3 is multiplied by 2/2 to become 2/6. Thus the two fractions will have the same denominator, which is 6. After both fractions have the same denominator, the next step is to add up the numerators, 3 + 2 = 5.

So 1/2 + 1/3 = 5/6.


Example Problem 3: Addition of Regular Fractions

Count: 3/4 + 4/5 = …?

Answer: So 3/4 + 4/5 = 31/20, or we can simplify it again into a mixed number 1 11/20.

Example Problem 4: Addition of several Regular Fractions

Count: 1/2 + 2/3 + 5/6 = …?

Answer:

Even for three fractions, the method remains the same, we must first equalize the denominator (become 6). 1/2 is changed to 3/6; 2/3 becomes 4/6. After that, we just add the three fractions to 12/6 or if simplified they are equal to 2. So 1/2 + 2/3 + 5/6 = 12/6 = 2.

There are several types of subtraction numbers that you need to know, including the following:

Reduction of Ordinary Fractions

An ordinary fraction is a fraction with a numerator as well as a denominator with an integer system.

Examples are: 2/4, 3/5, 8/9.

In the subtraction principle system in ordinary fractions, the concept is the same as the addition concept in ordinary fractions that was previously discussed, namely by reducing the numerator only. If the number to be subtracted has a different denominator, then you have to match the denominator first. If you want the easiest way, just multiply the number of the denominator if you can’t find the simplest value to match the denominator.


Example

The method above is the simplest way, namely by using the calculation operating system in the KPK, which is 2 and also 6 is 12. For the denominator or numerator, you must multiply it on the same KPK number.

Pure Fraction Reduction

The second fraction, which is a pure fraction, is a fraction that has integers in the numerator and denominator. This of course applies to the numerator where it must be less or can be said to be smaller than the denominator.

In this case you can also call a pure fraction as an ordinary fraction, but ordinary fractions cannot be said to be members of a pure fraction. You can see an example of a pure fraction below: For example: 2/4, 4/5, 8/10
