1. Answer:

   7/18

   Step-by-step explanation:

   Let the numerator of fraction be x

   so, denominator is 2x+4

   If 6 is subtracted from both, denominator becomes 12 times the numerator.

   According to question:-

   12(x-6) = 2x+4-6

   12x – 72 = 2x – 2

   12x – 2x = 72 – 2

   10x = 70

   x =70/10

   x = 7

   so, the fraction is : x/2x+4

   7/2(7)+4

   7/14+4

   7/18
