Question

Of the 50 students in the cafeteria, 7 have red hair. If there are 750 students in the school, predict the number of students who have red hair.

Answer 1

105 students have red hair

Explanation:

We are told that 7 of 50 students in the school cafeteria have red hair; this works out to 14%.

Predict the number of students who have red hair by multiplying the total 750 students by 0.14:

0.14(750 students) = 105 students have red hair

Answer 2

105

Explanation:

750 divided by 50 = 15

15 x 7 = 105
