Question 990827
Hi dear,
the fraction is 3/5.
HERE IS THE WORKING:
Let the fraction be x/y
Then,from your first sentence, 
{{{(x+3)/(y+3)=3/4}}}
4(x+3)=3(y+3)
4x+12=3y+9
4x-3y=-3----(1)
From your second sentence,
{{{(x-1)/(y+1)=1/3}}}
3(x-1)=y+1
3x-3=y+1
3x-y=4----(2)
Fro equ 2,
y=3x-4---(3)
put 3 in 1
4x-3(3x-4)=-3
4x-9x+12=-3
-5x=-15
x=3
put x=3 in equ 3
y=3(3)-4
y=9-4
y=5
Then,the fraction becomes 3/5
HOPE THIS HELPS?
