Add and Subtract Like Fractions

For Example

To add (or subtract) like fractions, add (or subtract) the numerators, and put the result over the common denominator.

For example, let's find the sum:

6
12
+
4
12


Observe that the denominator is same in both the fractions.

So, add the numerators, and put the obtained result over the common denominator.

6
12
+
4
12
=
6 + 4
12
=
10
12


Now, simplify:

10
12
=
10 ÷ 2
12 ÷ 2
=
5
6
So, 
6
12
+
4
12
=
5
6
