let the fraction be p/q
then,
(p+2)/q = 1/2
2p + 4 =q
and p/(q-1)=1/3
3p =q-1
q=3p+1
So
2p+4 = 3p+1 ;
4 -1 = 3p-2p;
p=3
q= 3*3 +1 =10
Therefore p=3 and q=10
So the fraction is 3/10
then,
(p+2)/q = 1/2
2p + 4 =q
and p/(q-1)=1/3
3p =q-1
q=3p+1
So
2p+4 = 3p+1 ;
4 -1 = 3p-2p;
p=3
q= 3*3 +1 =10
Therefore p=3 and q=10
So the fraction is 3/10

Answer:
3/10
Step-by-step explanation:
Let the fraction be x/y
X+2/y=1/2
2x+4=y
2x-y=-4--------(1)
X/y-1=1/3
3x=y-1
3x-y=-1----------(2)
3x-y=-1
2x-y=-4
X=3
3(3)-y=-1
-y=-10
Y=10
