The easiest way is to convert everything to cents first.
- Seven nickels = 35 cents
- Two quarters = 50 cents
- so 7 nickels to 2 quarters is the same as 35/50, or 0.7 as a decimal number.

2 quarters 3 dimes 8 nickels and 7 pennies equal $1.27
To make 60c, you can have no more than 2 quarters, because if you had 3 quarters that would make 75c, which is too much. So, you could make 60c with no quarters and some nickels, 1 quarter and some nickels, or 2 quarters and some nickels. If you have no quarters, you would need 12 nickels (12 x 5 = 60) if you had 1 quarter, you would need 7 nickels (7 x 5 = 35, 35 + 25 = 60) If you had 2 quarters, you would need 2 nickels (2 x 5 = 10, 25 x 2 = 50, 10 + 50 = 60) So, if you have to make 60c using quarters AND nickels, there are two different ways to do it: 1 quarter + 7 nickels 2 quarters + 2 nickels
