If Isaac has 4 times as many dimes as nickels and they have a combined value of 225 cents, how many of each coin does he have?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

Group his coins in the sets of 4 dimes and 1 nickel each.
The worth of each set is 4*10+5 = 45 cents.
The number of these sets is 225%2F45 = 5.

Answer. Isaac has 5 nickels and 4*5 = 20 dimes.
