dozen	1	10

answer
the best description for the strategy that he used is
submit answer
options: counting on, doubling, multiplying

Explanation:

Step1: Analyze the ratio table

The ratio table shows that 1 dozen corresponds to 12 doughnuts, and 10 dozen corresponds to 120 doughnuts. To find the number of doughnuts in 10 dozen, we can see that we multiply the number of dozens (10) by the number of doughnuts per dozen (12), i.e., \(10\times12 = 120\).

Step2: Evaluate the strategies

• "Counting on" involves adding repeatedly, which isn't the case here.
• "Doubling" involves multiplying by 2, but here we multiply by 10.
• "Multiplying" fits as we multiply the number of dozens (10) by the doughnuts per dozen (12) to get the total doughnuts.

Answer:

multiplying
