To add (or subtract) unlike fractions, first change them to fractions with same denominator. Then, add (or subtract) the numerators and put the result over the common denominator.

For example: Let’s add the fractions
1 2
and
1 4
.

Notice that the denominators of both the fractions are not the same.

So, let’s change them to fractions with same denominator.

Find the equivalent fraction of
1 2
having denominator 4.

 1 2
=
 1 × 2 2 × 2
=
 2 4

Now, add the fractions. Add the numerators and put the obtained result over the common denominator.

 1 2
+
 1 4
=
 2 4
+
 1 4

 2 + 1 4
=
 3 4

So,
