In the garden, the gecko eats 12 bugs. The lizard eats half as many bugs as the gecko. The frog eats 3 times as many bugs as the lizard. The toad eats 50% more bugs than the frog. How many bugs are eaten in total by all of them?
Thoughts? Step-by-step reasoning:
Lizard eats 12 / 2 = 6 bugs. Frog eats 6 x 3 = 18 bugs. Toad eats 18 x 1.50 = 27 bugs. The lizard, frog and toad eat 6 + 18 + 27 = 51 bugs. Adding what the gecko eats, a total of 12 + 51 = 63 bugs are eaten.
Thus, the answer is 63.
