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
