Answer:
A. 5%
B. 71.25%
Step-by-step explanation:
A. 80 people were surveyed, 4 of the people surveyed exercise for at most 45 minute.
100 divided by 80 = 1.25
1.25 times 4 = 5
B. 80 people were surveyed, 57 of the people surveyed exercise for more than an hour and a half.
100 divided by 80 = 1.25
1.25 times 57 = 71.25
sorry I don’t know the last one.
