Fractions 97

Let’s Attempt

Example 1: Which of the following are groups of like fractions?
2 3 4 5 5 6 13 14 6 7 8 9
(a) , , , (b) , , , (c) , , ,
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.
Now, arrange the numerators in ascending order: 2 < 3 < 4 < 5.

2 3 4 5
Thus, the ascending order of fractions is: < < <
