Answer 1

Answer:

25/37

Step-by-step explanation:

Let the numerator is x

Then the fraction is x/x+12

If 3 is added to denominator and 5 is added to the numerator

Then x+5/x+12+3= x+5/x+15

Is equal to 3/4

Then x+5/x+15=3/4

By cross multiplication method

4(x+5)=3(x+15)

4x+20=3x+45

4x-3x=45-20

X=25.

Then the actual fraction is

25/37
