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

ioda

Answer:

The fraction will decrease $33.33\%$

Step-by-step explanation:

Let

x/y ----> the fraction

we know that

100%-50^=50%=50/100=0.50

100%-25%=75%=75/100=0.75

substitute

$\frac{x}{y}*\frac{0.50}{0.75} =\frac{2}{3}(\frac{x}{y})$

therefore

The percent that the fraction will decrease is equal to

$(1-\frac{2}{3})*100=33.33\%$
