Answer:
2/5
Step-by-step explanation:
Let x = numerator
3 + x = denominator
[tex]\frac{x}{3+x}[/tex]
the numerator and denominator are increased by 1 , the fraction becomes
[tex]\frac{x + 1}{4 + x} = \frac{1}{2}[/tex]
cross multiply
2(x + 1 ) = 4 + x
2x + 2 = 4 + x
combine like terms
2x - x = 4 - 2
x = 2 = numerator
denominator = 2 + 3 = 5
2/5 fraction
