Now, we find the multiples of the denominator till the fourth place. So, we

have 3, 6, 9, and 12.
2 4 6 8
Hence, the equivalent fractions are = = = .
3 6 9 12
Checking Equivalence of Fractions

To check whether given fractions are equivalent or not, we follow the cross multiply

rule given below :

F Multiply the numerator of the first fraction with the denominator of the second
fraction and the denominator of the first fraction with the numerator of the second

fraction.

F Compare both the products, if they are equal, then the fractions are equivalent,
otherwise not.

7 21
Example : Check whether and are equivalent fractions.
9 27

Solution : 7 21

9 27

7 × 27 and 9 × 21

= 189 and 189

Both the products are equal.

7 21
Hence, and are equivalent fractions.
