coMParing and ordEring Fractions
comparing like Fractions
We know that like fractions are fractions with same denominator.
If the fractions are like fractions, then the fraction having greater numerator is greater.
example 1: Compare the following:
4
3
5
7
(a) and (b) and (c) 7 and 5
5 5 8 8 10 10
Solution: Look at the given pairs of fractions and compare them by observing diagrams.
5
3
4
7
(a) and (b) and (c) 7 and 5
5 5 8 8 10 10
4 > 3 5 < 7 7 > 5
5 5 8 8 10 10

Look at the adjoining figure; for , the strip has been divided into 2 equal
parts and shaded one part. 2
1
For , the same strip has been divided into three equal parts and shaded one part.
3
Clearly, 1 shaded part out of 2 equal parts is larger than 1 shaded part out of 3 equal
parts.

For Fractions Having different numerators and denominators
Change the fractions into their respective equivalent fractions with the same denominator
by finding the LCM of the denominators of the given fractions. Compare them as like
fractions.
