Hello!

Here are two ways to solve this problem. Way 1:

Convert the fraction to a decimal by dividing its numerator by its denominator.

2 ÷ 3 = 0.6666666667

Then, multiply the decimal by the total amount of books.

0.6666666667 × 12 = 8

Way 2:

Divide twelve by the denominator of the fraction, and then multiply it my the numerator.

12 ÷ 3 = 4

12 × 2 = 8

Thus, 8 of the 12 books are science fiction.
