Question

You are a technician in a biology lab. You need to separate mice into equal groups. There are 84 mice altogether. You are instructed to place 12 mice in each cage. How many cages do you need?

a) 6
b) 7
c) 72
d) 96
e) 1,008

Answer 1

To place 84 mice, each cage holding 12 mice, you would need b) 7 cages.

Step-by-step explanation:

To determine the number of cages needed, you divide the total number of mice by the number of mice per cage. In this case, 84 mice divided by 12 mice per cage equals 7 cages. Each cage can accommodate 12 mice, and you distribute the mice equally into the available cages.

Option B, 7 cages, is the correct answer. Options A, C, D, and E are not accurate based on the given scenario. It's essential to perform such calculations accurately, especially in a laboratory setting, to ensure the proper organization and care of the experimental subjects.

Option B is the answer.
