Question

At the used bookstore, Keisha bought 24 novels. If 3/8 of the book the books are mystery novels and the rest are science fiction novels, how many science fiction novels did Keisha buy?

Answer 1

Keisha bought 15 science fiction novels.

Step-by-step explanation:

Given,

Number of novels bought by Keisha = 24

Mystery novels = 3/8 of total novels

Mystery novels = $\frac{3}{8}*24=\frac{72}{8}$

Mystery novels = 9

Let,

x represent the number of science fiction novels.

Mystery novels + Science fiction novels = Total novels

$9+x=24\\x=24-9\\x=15$

Keisha bought 15 science fiction novels.
