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?
Step-by-step reasoning process below:
66
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.

.

The answer: 66
