When a grizzly bear hibernates, its heart rate drops to 10 beats per minute, which is 20%, percent of its normal value. What is a grizzly bear's normal heart rate when not hibernating?

Answer:

50

Explanation:

20% is 1/5 of 100. So you multiply 10 by 5 and you get 50.

To find the answer, you set up an equation:

You put the 20% into decimal form by sliding the decimal place two spaces to the left. The "x" represents the grizzly bear's normal heart rate.

10 = .20x

Now, you divide both sides by .20

You should get:

50 = x

A grizzly bear's normal heart rate when it is not hibernating is 50 beats per minute.
