Question

15. The denominator of a fraction is 4 more than twice its numerator. Denominator becomes 12 times the numerator, if both
numerator and the denominator are reduced by 6. Find the fraction.​

Answer 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
