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?
Lizard eats 12 / 2 = <<12/2=6>>6 bugs.
Frog eats 6 x 3 = <<6*3=18>>18 bugs.
Toad eats 18 x 1.50 = <<18*1.50=27>>27 bugs.
The lizard, frog and toad eat 6 + 18 + 27 = <<6+18+27=51>>51 bugs.
Adding what the gecko eats, a total of 12 + 51 = <<12+51=63>>63 bugs are eaten.
