a) Looking at the chart, we can see that the "At least twice a week" section takes up 2/5 of the total chart (since there are 5 equally-sized sections and "At least twice a week" is made up of 2 of those sections). Therefore, the fraction of people surveyed who said they exercise at least twice a week is 2/5.
b) Since 2/5 of the people surveyed said they exercise at least twice a week, we can set up the following equation:
2/5 = x/4140
where x is the number of people who said they exercise at least twice a week. To solve for x, we can cross-multiply to get:
5x = 2 * 4140
5x = 8280
x = 1656
Therefore, 1656 people said that they exercise at least twice a week.
This pie chart is split into equal sections. It shows the results from a survey about how often people exercise.
a) What fraction of the people surveyed said that they exercise at least twice a week? Give your answer in its lowest terms.
b) If 4140 people answered the survey in total, how many people said that they exercise at least twice a week?
