Question

Josh has a collection of 110 comic books. Eighty-two of the comic books feature superheroes. What percent of the comic books feature superheroes? Round to the nearest percent, if necessary.

Answer 1

So,

Josh has 110 comic books total, and 82 of them feature superheroes.  To find the percentage, just divide 82 by 110.

$\frac{82}{110} = \frac{2*41}{2*5*11} = \frac{41}{55}$

$\frac{41}{55}=0.7\overline{45}$

To convert to a percent, just move the decimal place two places to the left and add a percent sign.

$0.7\overline{45} --\ \textgreater \ 74.\overline{54}\ percent$

Rounding, we get:

75%

So about 75% of Josh's comic books feature superheroes.
