Question

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?

Answer 1

Dimes: 200

Quarters: 320

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
