**Steve**, Tuesday, November 22, 2011 at 5:31amIf the fraction is a/b

(a+1)/(b+1) = 1/2

(a+8)/(b+8) = 2/3

2a+2 = b+1

(1): 2a - b = -1

3a+24 = 2b + 16

(2): 3a - 2b = -8

subtract 2x#1 from #2

3a - 2b = -8

4a - 2b = -2

-a = -6

a = 6

so, b = 13

Original fraction: 6/13

Check:

(6+1)/(13+1) = 7/14 = 1/2

(6+8)/(13+8) = 14/21 = 2/3
