50%. If the numerator of the original fraction is "a" and the denominator is "b", then the original fraction is "a/b" and the modified fraction is "3a/2b". To determine the relationship between these two quantities (if it isn't obvious already), divide the second one by the first: (3a/2b)/(a/b) = 3/2. So, the modified fraction is 3/2 as large as the original fraction, an *increase* of 1/2 or 50%.
