If the numerator of a fraction is multiplied by 4 and the denominator is reduced by 2 the results is 2.If the number of the fraction is increased by 15 and 2 is subtracted from the double of the denominator the results is 9/7 find the fraction
4n/(d-2) = 2
(n+15)/(2d-2) = 9/7
solve for n and d, and you see the original fraction is n/d = 3/8
