The numerator of a certain fraction is four times the denominator. If 6 is added to both the numerator and the denominator, the resutling fraction is equivalent to 2. What was the original fraction ?
original fraction is 4x/x, clearly not in lowest terms of 4
solve (4x+6)/(x+6) = 2
I get x = 3
so the original fraction was 12/3, which of course should have been reduced to 4.
(I really don't like this question, sloppy planning mathematically.)
