A survey shows that four out of every seven students watch TV more than three hours per day. If there are 560 sophomores in a high school, how many would you expect to watch more than three hours of TV every day?

Sagot :

(4/7) (560) = number of students who watch TV more that three hours every day.

(4)(560)      = 2240      = 320
    7                 7

There are 320 students who watch TV more than three hours a day.
