Beth is looking at her book collection and is wondering how many comic books she owns. She has 120 books and 65% are novels. 18 are graphic novels. The rest are comic books. What percentage of comic books does she own?
The proportion of graphic novels is .15 because 18 / 120 = <<18/120=.15>>.15
The percentage of graphic novels is 15 because 100 x .15 = <<100*.15=15>>15
The percentage of comic books is 20 because 100 - 65 - 15 = <<100-65-15=20>>20
#### 20
