Use a ratio box to solve this problem. There was a total of 520 dimes and quarters in the soda machine. If the ratio of
dimes to quarters was 5 to 8, how many dimes were there?

Dimes:    200

Quarters:     320

Step-by-step explanation:

Construct a table as follows

Item          Dimes          Quarters          Total

Ratio         5                  8                       13

Actual       d                  q                       520

Note that any two ratios of corresponding quantities are the same.

(d/5)=(520/13)=40

d=200

(q/8)=(520/13)=40

q=320

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
