Question

Convert given fraction into a fraction with equal numerators: 

`15/19, 25/28, 9/11  "and"  45/47`

Answer 1

In `15/19, 25/28, 9/11  "and"  45/47`,
L.C.M. of 15, 25, 9 and 45 = 225

`therefore 15/19 = (15 xx 15)/(19 xx 15) = 225/285`

`25/28 = (25 xx 9)/(28 xx 9) = 225/252`

`9/11 = (9 xx 25)/(11 xx 25) = 225/275`

and `45/47 = (45 xx 5)/(47 xx 5) = 225/235`

Hence the required fractions are `225/285, 225/252,  225/275 "and"  225/235`
