Grade 7 students were surveyed to determine how many hours per day they spent on various activities. The results are shown in the circle graph below. About how many hours per day altogether were spent on watching TV and homework?
A Pie Chart is titled • The pie chart slices are as follows:
• "Homework" at 8%
• "Watching TV" at 13%
• "Socializing" at 13%
• "School" at 25%
• "Sleeping" at 33%
• "Eating" at 8%
A. about 6 hours
B. about 7 hours
C. about 4 hours
D. about 5 hours
To find out how many hours per day were spent on watching TV and homework, we need to add the percentages of the "Watching TV" and "Homework" slices together.
13% + 8% = 21%
So, about 21% of the day's hours were spent on watching TV and homework.
Since the chart shows the total day being divided into six categories, we know that 100% of the hours in a day must be accounted for.
This means that the remaining 79% hours were spent on Socializing, School, Sleeping, and Eating.
We can conclude that the answer is: About 5 hours spent on watching TV and homework.
