Answer:
22.4
Explanation:
If the sloth is 28 years old, the following equation can be used to find the amount of years it spends asleep:
4/5(28) = # of years the sloth spent sleeping.
Now, multiply 4/5 by 28
4/5(28) = 22.4
So, the sloth spent about 22.4 years of its life asleep (round to 22 whole years if you'd like)
