Question

a fraction becomes 1 by 3 1 1 is subtracted from the numerator and it becomes 1 by 4 1 18 is added to the denominator find a fraction

Answer 1

Answer:

Step-by-step explanation:

Let the fraction be x/y

(x - 1)/y = 1/3 => 3(x - 1) = y

x/(y + 8) = 1/4 => 4x = y + 8 => y = 4x - 8

3(x - 1) = 4x - 8 => 3x - 3 = 4x - 8 => x = 5

y = 4x - 8 = 20 - 8 = 12

(x/y) = 5/12
