If you have four quarters, three dimes, two nickels, and two pennies, what fraction of the whole coin collection is in dimes?

4 quarters + 3 dimes + 2 nickels + 2 pennies = 11 coins total

We are interested in finding out how much of the collection is dimes only --> 3 dimes / 11 total = 3/11.

To find the fraction of how many dimes there are, add up all the coins.

$$4+3+2+2 = 7+4 = 11$$

Now, because you have the total number of coins, count how many dimes there are and then, write the fraction.

Answer:  $$3/11$$
