5 geckos on the kitchen window eat 6 insects each. 3 lizards eat twice as much as the geckos. How many total insects were eaten?
Thoughts? Step-by-step reasoning:
The number of insects the geckos eat is 5 x 6 = 30. The number of insects the lizards eat is 3 x 12 = 36. The total number of insects eaten is 30 + 36 = 66 insects.
Thus, the answer is 66.
