Question

Suppose a college surveyed its students and found that two-thirds of them sleep at least seven hours each night. on a campus of 918 students, how many students could be expected to sleep at least seven hours each night?

Answer 1

The answer is 606 students.

2/3 is equivalent to 0.66

You multiply 918 and 0.66

918 x 0.66 = 605.88.

You round 605.88 to the nearest whole which is 606 students.
