Question

The denominator of a fraction is 5 more than the numerator. If the numerator is increased by 18 and the denominator is decreased by 4,the fraction becomes 25/8.Find the fraction​

Answer 1

Answer:

7

Step-by-step explanation:

old fraction = x/x+5

new fraction = x+18/x+5-4 = x+18/x+1

fraction = 25/8

fraction = x+18/x+1

25/8=x+18/x+1

cross-multiply 25 with x+1 & 8 with x+18

25x + 25 = 8x + 144

25x - 8x = 144 - 25

17x = 119

x = 119/17

x = 7
