Steps to Add Two Fractions

Fraction is a part of the whole thing. Mathematically, it can be represented as a/b here a is the numerator and b is the denominator. Adding two fractions means getting the sum of them. The following mentioned are the steps to calculate the addition of fractions. Go through the guidelines and find the answer.

  • Addition of Like Fractions:
    • Note down any two fractions.
    • As denominators of the fractions are same, add the numerators.
    • The resultant fraction is the addition of like fractions.
  • Addition of Unlike Fractions:
    • Get two fractions with different denominators.
    • Find the least common multiple of denominators.
    • Multiply the numerators and denominators to get the LCM in all denominators.
    • Add the numerators and write the total fraction.

Example Questions on Sum of Fractions

Example 1

Add fractions 13/21 + 15/16?


The given fractions are 13/21 and 15/16

Find L.C.M of two denominators i.e 21, 16 is 336

13/21 + 15/16 = (13x16 + 15x21)/336

= (208 + 315)/336

Therefore, 13/21 + 15/16 = 523/336.

Example 2

Add fractions with same denominators 1/8 + 5/8


Given two fractions are 1/8 and 5/8

As the denominators for both the fractions are the same you can add the numerators simply to add fractions while leaving the denominator unaltered.

1/8 + 5/8 = (1 + 5)/8

= 6/8 = 3/4

Therefore, 1/8 + 5/8 = 3/4.

Example 3

Add fractions with different denominators 7/4 + 4/5


Given fractions are 7/4, 4/5

L.C.M of 4, 5 is 20.

Multiplying numerators and denominators to get the LCM in all fraction denominators

7/4 + 4/5 = (7 x 5)/20 + (4 x 4)/20

= 35/20 + 16/20 = 51/20

Therefore, 7/4 + 4/5 = 51/20.

FAQs on Adding Fractions

1. How to add fractions with unlike denominators?

Fractions with unlike denominators means having different denominator. The simple step is to find the LCM of denominators and add the numerators.

2. Find sum of 2/5 + 1/3?

Two unlike fractions are 2/5, 1/3

LCM of 5, 3 is 15

2/5 + 1/3 = 6/15 + 5/15 = 11/15

3. How to add fractions to whole numbers?

To add a whole number to the fraction, convert the whole number into a fraction by placing 1 in the denominator. Now, compare the denominators, make them common and add numerators.
