Question

The denominator of a fraction is three more than twice the numerator. if both numerator and denominator are degreased by seven, the simplified result is 4/13

orgnal fraction. (Don't simplify.)

Answer 1

2/7

Explanation:

d=2n+3

`(d-7)/(2n-4) = (4)/(13)`

13(2n+3) -91 =8n - 16

26n+39 -91 = 8n-16

18n=36

n=2

d=7
