For your first question, the first sentence answers it, "12 nickels,dimes,and quarters in his pocket."
For the dime, 1/4 of 12 = 3
As I indicated before, there is not enough data to tell how many of the remaining 9 coins are nickels or quarters. Do you have more information that you have not included, for instance, the total value of the coins?
