Answer 1

Answer:

x=107/2

Step-by-step explanation:

let numerator be x

denominator is greater than its numerator by 6

= x+6

numerator is increased by 15 = x+15

and denominator is decreased by 2 = x+6-2= x+4

therefore ,. x+15 7

--------- = --------

x+4 9

9(x+15) = 7(x+4)

9x+135 = 7x+28

9x-7x = 28-135

2x = 107

x = 107/2
