Question

a fraction becomes 1 /3rd when 1 is subtracted from the numerator and it becomes 1 /4 when 8 is added to the denominator find the fraction

Answer 1

Answer:

The fraction is x/y=5/12

Step-by-step explanation:

Let the fraction be x/y

the fraction becomes 1/3when 1 is subtracted from the numerator

X-y/y=1/3

By cross multiplication we get

3x-3=y........... (1)

and it becomes 1/4 when it is added to the denominator

X/y+8=1/8

4x=y+8

on putting the value of Y in equation first we get

4x=3x-3+8

X=5

Putting the value of x in eq 1

3*5-3=y

Y=15- 3

Y=12.
