There are two answers, and possibly a third. One is by face value: 4 quarters, 3 dimes, 2 nickels, and 2 pennies is $1.42, of which 30 cents are dimes. The fraction is therefore 30/142, which reduces to 15/71. A second one is by coin count: 4 quarters, 3 dimes, 2 nickels, and 2 pennies is 11 coins, of which 3 are dimes.

How many total amounts can you make with 4 items?

As no combinations of your coins add up the the same amount the number of amounts is the number of subsets of coins. With 4 items there are 2 4 = 16 subsets, so you can make 16 different totals. If you don’t want to count 0, subtract 1.
