The denominator of a fraction is 4 more than the numerator. If both the denominator and the numerator are increased by 1, the resulting fraction equals 1/2. What is the original fraction?

**drwls**, Saturday, March 26, 2011 at 10:48pmThe fraction is x/(x+4), where

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

That can be rewritten

x+5 = 2(x+1)

which reduces to

x = 3

Therefore the fraction is 3/7

**Ms. Sue**, Saturday, March 26, 2011 at 10:49pmI used trial and error to come up with 3/7.

I started with 1/5 and 2/6, which of course doesn't work.
