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


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

Rounding, we get:
75%
So about 75% of Josh's comic books feature superheroes.

26
