Answer :

To find an equal ratio, just multiply both sides of the ratio by the same number.

12:7
12(2):7(2)
24:14

12:7 = 24:14
as 12:7 = 12/7
therefore to get equivalents of a fraction we multiply the nominator and the denominator with a same no
let us take 2
then, 12x2/7x2 =24/14
your ans is 24/14
