Answer» Answer: 5/7 Sum is 12 so LET the numerator be x and denominator is 12 - x . THUS fraction formed = x/12 - x Now according to the question, x/ 12 - x + 3 = 1/2 x / 15 - x = 1/2 by CROSS multiplication, 15 - x = 2x 15 = 3x 5 = x So the numerator of fraction is 5 and denominator is 12 - x = 12 - 5 = 7 So the fraction formed is 5/7.
