Question 1070507
n = numerator
d = denominator.


(n + 1) / (d + 1) = 3/4


this means:


n + 1 = 3
d + 1 = 4


solve for n and d and you get:


n = 2
d = 3


the original fraction is 2/3.


it does not appear to be that you even needed to know that the numerator is less than the denominator, since solving the problem did not require that information.


that's what i think, anyway.
