Question

By what percent will a fraction decrease if its numerator is decreased by 50% and its denominator is decreased by 25%?

Answer 1

33 and 1/3 percent because the new fraction is 2/3 of the old fraction.

Answer 2

Answer:

33 2/3 %    (33.33%)

Step-by-step explanation:

Fraction = x/y

After decrease: (x - .5) / (y-.25)

Simplify :      .5x / .75y

                       = 2/3          

1 - 2/3 = 1/3 = .33 = 33 1/3 %

Hope this helps
