Exercise 2 Page 108

How many quarters are there? How many coins are there overall?

7 to 16, or 7 : 16

Practice makes perfect
We want to write the ratio of quarters to total number of coins using the given example. Within the example we found that there are 3 dimes, 7 quarters, and 6 pennies. Let's sum these numbers to find the total number of coins.

3 + 7 + 6 = 16 There are 16 coins overall and 7 of them are quarters. Therefore, the ratio of quarters to the total number of coins is 7 to 16, or 7 : 16.
