Mammals has these 3 groups .
Monotremes, marsupials, and placentals
If one fourth (1/4) of the mammals are bats, then the mammals that are not bats would be 3/4 of all mammals on Earth. Rationale: The whole is (all the mammals on Earth) = 4/4, 1/4 = bats 4/4 - 1/4 = 3/4 of the total mammals are not bats You could also calculate this in percentages. For example: The whole (all the mammals on Earth) = 100% 1/4 = bats 100 divided by 4 = 25 100% - 25% = 75% of the total mammals are not bats
