Question

find the fraction equivalent to 4/ 7 whose denominator is 12 more than it's numerator​

Answer 1

Step-by-step explanation:

Let the numerator be x

Denominator be x+12

4/7=x/(x+12)

Cross multiplying 7x= 4(x+12)

7x=4x+84

3x=84

x=28

Answer 2

Answer:

let the numerator be x

then denominator be x+12

ATQ, 4/7 is equal to x/x+1

this implies 4(x+12) =7(x)

4x+48=7x

48=7x-4x

48=3x

48/3=x

16=x

therefore the fraction =16/16+12=16/28
