Question

Usan has a collection of 105 nickels and dimes. If the number of nickels is six times the number of​ dimes, how many nickels and how many dimes does she​ have?

Susan has
____nickels and _____dimes.

Answer 1

90 nickels and 15 dimes

Explanation:

If one is six times the other, then you would have 7 equal piles. Divide 105 by 7 to get 15 which is the number in each pile(number of dimes). Then 105 minus 15 gives you the total of the rest of the piles(number of nickels).

Check:

90 plus 15 equals 105, and

15 times 6 equals 90.
