Question

the numerator of a number is less than its denominator by 3 . if numerator becomes 3 times and denominator is increased by 20 the new number becomes 1/8 , find the fraction ​

Answer 1

Answer:

x = 1

Step-by-step explanation:

let the numerator be x

the fraction = x/x + 3

now when numerator becomes 3 times and denominator is increased by 20

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

3x/x+23 = 1/8

Cross multiply lhs and rhs

3x (8) = x+23 (1)

24x = x+23

24x-x = 23

23x = 23

x = 23/23 = 1

the fraction = 1/1 + 3 = 1/4
