Comparison of Like Fractions

When denominators of the given 3 2 1
fractions are same, fraction with the 4 4 4
greatest numerator is the greatest.

Order of numerators in the above fractions is 3 > 2 > 1.
3
2
1
So, order of fractions is > > .

4
Let's Try

Example 1: Which of the following are groups of like fractions?

2
5 6 13 14
(a) , 3 , 4 , 5 (b) , , , (c) 6 , 7 , 8 , 9
7 7 7 7 6 5 15 17 10 10 10 10
Solution: (a) and (c) are two groups of like fractions as they have fractions with the

same denominator.
2 5 3 4
Example 2: Arrange , , , in ascending order.
9 9 9 9
Solution: All the fractions have same denominator. The numerators of the

fractions are 2, 5, 3, 4 and in ascending order they are

2
2 < 3 < 4 < 5, so, < 3 < 4 < 5 .
9 9 9 9

Thus, the ascending order of fractions is:

2 , 3 , 4 , 5
9 9 9 9
