When a grizzly bear hibernates, its heart rate drops at 10 beats per minute, which is 20% of its normal value what is a grizzly bears normal heart rate when not hibernating?

Divide the current beats per minute by the percentage to get the original beats per minute.

= 10 beats ÷ 20%
= 10 ÷ 0.20
= 50 beats per minute

Check:
= 50 beats * 20%
= 50 * 0.20
= 10

Hope this helps! :)

What's the denominator
