If the numerator of a fraction is decreased by 40% and the denominator is increased by 100%, the new value is 1. What was the original fraction?
Answer
Let the original fraction be X/Y
So, the new fractions is
(1 - 0.4)X/ 2Y = 1
or 0.6 X / 2Y = 1
or X/Y = 1 x 2/0.6
or X/Y = 20/6
Answer
Let the original fraction be X/Y
