Question

the denominator of a fraction is 4 more than the twice its numerator, when both the numerator and denominator are decreased by 6, then the denominator becomes 12 times the numerator. Find the fraction.​

Answer 1

Answer:

7/18

Step-by-step explanation:

Let the fraction be x/y then :

y = 4+2x

(y-6)=12(x-6)

4+2x - 6 = 12x - 72

-2 = 10x -72

10x = 70

x = 7

y = 4+2*7 = 4+14 = 18
