Ratios & Proportions Example 1

At a local book store, for every one hundred books sold, 68 of them are fiction. What is the proportion of nonfiction books sold?

Since 68 of every 100 sold are fiction, it’s a safe bet that the remaining books are nonfiction. So, 100 - 68 = 32 nonfiction books for every 100 sold. Proportions are usually written as fractions, so:

32/100, which reduces to (by dividing by 4) 8/25.
