The ratio of nickels to dimes that Wade had saved in his bank was 10/13. If total number of nickels and dimes saved was 391, how many of them were dimes?

The answer is 221.

Step-by-step explanation:

It is 221 because you find what number you can multiply both sides of the ratio by to get 391.

If you add both sides, 10 and 13, you get 23.

Divide 391 by 23 and you get 17.

Finally, multiply 13 by 17 and you get 221.
