Question

the numerator of a fraction is 3 less than the denominator if 1 is added to both the numerator and denominator it becomes 1 upon 2 find the fraction. step wise answer plzzzz

Answer 1

Let denominator =x
then numerator=x-3

When 1 is added to both


Numerator=(x-3+1)=x-2
Denominator=x+1

x-2/x+1=1/2
2(x-2)=x+1
2x-4=x+1
2x-x=1+4
x=5

Numerator=(5-3)=2
Denominator=5
