How many quarters have the same value as 85 dimes? use the equality 4 quarters = 10 dimes.?

34 quaters have the same value as 85 dimes.

Explanation:

We are given a conversion factor:

10 dimes = 4 quaters

We need to find out the value of 85 dimes. For that we use unitary method.

If 10 dimes have the same value as 4 quaters.

So, 85 dimes will have the same value as quaters.

Hence, 34 quaters have the same value as 85 dimes.
