Question

The numerator of a rational number is less than its denominator by 3 if the numerator becomes three times and the denominator is increased by 20 the new number becomes 1by8 find the original number

Answer 1

Let the denominator be x,then numerator will be x-3

so,the fraction is x/(x+3)

Now,

Acccording to question

3x/(x+3+20) =1/8

24x/(x+23) =1

24x=x+23

x=23

so, numerator=23

denominator=x+3=23+3=26

so, fraction is,23/26
