At Brian’s Bookstore, 0.3 of the shelves hold mysteries, 25% of the shelves hold travel books, and \(\frac{7}{20}\) of the shelves hold children’s books. Which type of book covers the most shelf space in the store?

Explain how you arrived at your answer.

There are multiple ways to answer this, because one would have to convert all of the numbers into a percentage, decimal, or fraction. Let's go with percentage. Travel books = 25% is already a percentage, so you don't have to worry about it. Mystery books = 0.3 is easy to convert. 1 = 100%, so 0.3 = 30%. See? Easy. Children books = 7/20 is the hardest, although it isn't THAT hard. Any percentage means "this number out of a hundred", and 20 is one-fifth of one hundred. So, we can multiply the fraction by one, essentially, in this form: 7/20 * 5/5. This equals 35/100, which is 35%. We have 25%, 30%, and 35%. Children's books take up 35%, which is the largest amount .
Comment if you want me to convert them into either decimals or fractions (or both).

Children's books cover the most shelf space in Brian's Bookstore at 35%, which is more than the 30% for mysteries and 25% for travel books.
