At Brian’s Bookstore, 0.3 of the shelves hold mysteries, 25% of the shelves hold travel book and 7/20 of the shelves hold childr

Children books covers the most shelf space in the store

Solution:

From given,

Shelves that hold Mysteries = 0.3

Shelves hold travel book = 25 %

Shelves hold children’s books = $\frac{7}{20}$

To find: Type of book that covers the most shelf space in the store

You cannot compare values which are in different forms, so you need to convert.

Let us convert the given values into decimal form

Shelves hold travel book = 25 %

Percentage can be converted to decimal by dividing by 100

$\rightarrow 25\% = \frac{25}{100} = 0.25$

Shelves hold children’s books = $\frac{7}{20}$

$\rightarrow \frac{7}{20} = 0.35$

Which type of book covers the most shelf space in the store?

Now we have converted them into decimal form

Shelves that hold Mysteries = 0.3

Shelves hold travel book = 0.25

Shelves hold children’s books = 0.35

$0.35>0.3>0.25$

We can clearly see that, 0.35 is the highest decimal

Therefore, children books covers the most shelf space in the store
