Question

the denominator of the fraction is 3 more than the numerator. if 5 is added to both parts, the resulting fraction is equivalent to 4 by 5. find the fraction

Answer 1

Let the numerator be x
Then, the denominator will be x+3
ATQ
x+5/x+3+5=4/5
x+5/x+8=4/5
5 (x+5)=4 (x+8)
5x+25=4x+32
5x-4x=32-25
x=7

The fraction is 7/10

Answer 2

The denominator of the portion is 3 more than the numerator.

In case 5 is added to the two sections, the subsequent portion is proportional to 4 by 5.

At that point the part is - Let the numerator be x Then, the denominator will be x+3 ATQ x+5/x+3+5=4/5 x+5/x+8=4/5 (x+5)=4 (x+8) 5x+25=4x+32 5x-4x=32-25 x=7 The division is 7/10.
