By what percent will a fraction change if its numerator is decreased by 20% and its denominator is decreased by 60%?

Answer:

The fraction will increase by 100%

Step-by-step explanation:

Say the fraction is x/y. The question is telling us to decrease x by 20% (i.e. 0.8x) and to decrease y by 60% (i.e. 0.4y):

$= \frac{0.8x}{0.4y}\\= 2 (\frac {x}{y})$

You can see that by applying these changes, the new fraction is actually double the old fraction (i.e. will increase by 100%).
