❖  Troy has 27 nickels.

First, subtract to find the remaining coins:

83 - 47 = 36

Percents are out of 100% so set up 75% as a fraction to find how many nickels. 75/100 can be simplified:

75 ÷ 25      3

         =  ---

100 ÷ 25     4

Multiply 3/4 by the remaining number of coins to get the number of nickels that Troy has:

3      36

--   x

4          

You can cross simplify:

3      9

--  x      =   27
