9. The denominator of a rational number is greater than its numerator by 5. If the numerator
is increased by 11 and the denominator is decreased by 14, the new number becomes 5.
Find the original rational number
let the numerator= x
so,denominator= x+4
number=x/x+4
according to Question,
= > 3(x+11)=7(x+3)
=> 4x = 12
=> x= 3
Hence the original number = 3/7
