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

Respuesta :

Lets just use [tex] \frac{10}{20} [/tex] for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being: [tex] \frac{16}{16} [/tex]. Since then new one is equal to 1, and the original is equal to [tex] \frac{1}{2} [/tex], we see that this manipulation of the fraction causes an increase of 100%.

Answer:

100%

Lets plug in numbers. Say the first fraction was 100/100.

100 increased by 60% = 160

100 decreased by 20% = 120

There you have your new fraction 160/120

you compare that to 100/100 ____ 160/120

Hence, it increases by 100%!
