Question

the denominator of a rational number is greater than by its numrator by 8.If a numrator is increased by by 17 and denominator is decreased by 1,the number is 3/2. Find the answer step by step

​

Answer 1

Answer:

13/21

Step-by-step explanation:

suppose numerator is x then fraction is x/x+8

now numerator increased by 17 and denominator decreased by 1 then fraction is (x+17)/(x+7)

given x+17/x+7=3/2 now cross multiply we get

2x+34=3x+21

so x=13

so fraction is 13/21
