Question

solve the problem..?

Answer 1

let the original numerator is x
and denomeneter is y
then

50%increase numerator is x+0.5×= 1.5x
denomeneter is doubled y×2 = 2y
then the new fraction is 1.5x/2y = 9/22
then calculate and the value is x= 6 & y= 11


and last it's 40% is (6/11)× (40/100) = 12/55
