Question

A fraction becomes 3/4 if 3 is added to both the numera
aided to both the numerator and denominator.
If 1 is subtracted from the numerator and 1 is added
numerator and 1 is added to the denominator, then it
becomes 1/3. Find the fraction.​

Answer 1

let number be x

numerator=x+3-1

denominator= x+3+1

x+3-1/x+3+1= 3/4+1/3

3x-1/3x+1=3/2

2[3x-1]=3[3x+1]

6x-2=9x+3

-2-3=9x-6x

-5=3x

x=-5/3
