# Maddie has 180 coins. Of these coins 1/12 are dimes. About how many dimes does she have?

$15$
You can interpret the fraction $\frac{1}{12}$ as "one part every twelve#. So, if you divide the whole number of coins into twelve parts, then one of these parts will be entirely composed by dimes.
So, you simply need to compute $\frac{180}{12} = 15$
