# Addition and Subtraction of Like Fractions

Here we will learn about addition and subtraction of like fractions.

Addition of Like Fractions:

In order to add two or more like fractions, we may follow the following steps:

**Step I**:

*Obtain the fractions*.

**Step II**:

*Add the numerators of all fractions*.

**Step III**:

*Retain the common denominator of all fractions*.

**Step IV**:

*Write the fraction as Result in Step II / Result in Step III*.

**For Example**:
Add the following fractions.

1.

^{1}/

_{6} +

^{4}/

_{6}

We have,

^{1}/

_{6} +

^{4}/

Subtraction of Like Fractions:

In order to subtract two like fractions, we may follow the following steps:

**Step I**:

*Obtain the two fractions and their numerators*.

**Step II**:

*Subtract the smaller numerator from the bigger numerator*.

**Step III**:

*Retain the common denominator*.

**Step IV**:

*Write the fraction as Result in Step II / Result in Step III*.

**For Example**:
1. Subtract

^{3}/

_{10} from

^{8}/

_{10}
*Solution*:

We have to find,

^{8}/

_{10} –

^{3}/

_{10}
=

^{(8 – 3)}/

_{10}
=

^{5}/

_{10}
=

^{(5 ÷ 5)}/

_{(10 ÷ 5)} [Dividing the numerator and denominator by their HCF (highest common factor) 5].

=

^{1}/

_{2}
2. Compute:

^{5}/

_{12} –

^{7}/

_{12} +

^{11}/

_{12}
*Solution:*
We have,

^{5}/

_{12} –

^{7}/

_{12} +

^{11}/

_{12}
=

^{(5-7+11)}/

_{12}
=

^{(11-2)}/

_{12}
=

^{9}/

_{12}
=

^{(9 ÷ 3)}/

_{(12 ÷ 3)} [Dividing the numerator and denominator by their HCF (highest common factor) 3].
