Suppose 60 people are asked which method is best to avoid getting the flu. the results are shown in the table below. determine the percentage for each method and complete the table. round to the nearest whole number.

method frequency %
flu shot 15
washing hands 36
taking vitamins 7
eating healthy foods 2

There are several information's already given in the question. Based on those given information's the answer can be easily deduced.

Flu shot = (15/60) * 100
              = 25%

Washing hands = (36/60) * 100
                          = 60%

Taking vitamins = (7/60) * 100
                          = 11.67%

Eating healthy foods = (2/60) * 100
                                  = 3.33%

I hope the procedure is clear enough for you to undersnad and also this is the answer that you were looking for.
