## How to Add Two Fractions with Different Denominators?

Users may refer the below example workout with step by step calculation to know how to add two fractions with different or unlike denominators.

__Problem & Workout__

Find what is the equivalent fraction by adding 5/6 and 3/4 (with unequal or different denominators).

step 1 Address formula, input parameters & values.

Input parameters & values:

5/6 & 3/4

5/6 + 3/4 = ?

step 2 For unequal denominators, *find the LCM (least common multiple) for both denominators*.

The LCM for 6 and 4 is 12.

step 3 To have common denominator, multiply LCM 12 with both numerators & denominators.

=(5 x 12)/(6 x 12)+(3 x 12)/(4 x 12)

=10/12+9/12

=(10 + 9)/12

step 4 Add both numerator and rewrite it in a single form.

5/6+3/4=19/12

Thus, **19/12** is the equivalent fraction by adding 5/6 and 3/4.

## How to Add Two Fractions with Same Denominators?

Find what is the equivalent fraction by adding 3/7 and 5/7 (with same, equal or common denominators).

step 1 Address formula, input parameters & values.

Input parameters & values:

3/7 & 5/7

3/7 + 5/7 = ?

step 2 For same denominators, add numerators directly and rewrite as below

= 3/7 + 5/7

= (3 + 5)/7

3/7 + 5/7 = 8/7

Thus,

**8/7**is the sum of 3/7 and 5/7.

### Fractions Addition & Formula

**Fraction Addition** is a basic arithmetic operation which combines two or more fractions. It's a part of most important elementary school mathematics. For same or common denominator, the fraction addition is the sum of both numerators divided by the common denominator. For unlike, unequal or different denominators, the function LCM (least common multiple) is used to convert the fractions to have the common denominators to perform addition between the fractions.
