Like and Unlike Fractions

Fractions with the same denominators are called like fractions.
1 2 7 3
For example, ,,, are all like fractions. Fractions with different denominators are called unlike
5 5 5 5
1 2 3 4
fractions. For example, ,,, are all unlike fractions.
3 5 7 9
We can convert unlike fractions into like fractions as explained below.
