Answer:
1 to 2
Step-by-step explanation:
If a bag contains 12 quarters, 6 dimes, and 18 nickles, what is the part-to-whole ratio of nickles to all coins?
Total number of coins: 12 quarters, 6 dimes, and 18 nickles add to 36 coins
Number of nickles: 18 nickles
Ratio of nickles to all coins:

Divide both numbers by 18 to get 1 to 2
