Question

A. There is a total population of 128 mice living under a house. The mice have either gray fur or black fur.

If 47 of the mice have gray fur, what percentage of the mice have black fur?

Answer 1

Answer: Since 81 mice have black fur, around 63.28% (Approx. 68.3%) of the mice have black fur.

Explanation: Evaluate the question carefully. We have a population of 128 mice, and 47 of them have gray fur, and the rest have black fur. That means that the other mice, besides the 47, have black fur.

`128 - 47 = 81`

To calculate percentages, I come up with proportions. 81 black fur mice over the total mice is equal to x over 100.

`(81)/(128) = (x)/(100)`

To solve the proportion, cross multiply and then divide.

`81 * 100 / 128 = 63.28125`

Round your answer to the nearest tenth.

`63.3`%
