Question

A survey of Mrs Hinds students showed that 30 students will have pizza for lunch, 17 will have macaroni and cheese, 12 will have hamburger, and 5 will have chicken nuggets. suppose Mrs Hind surveys all 1200 students in the school how many students can she expect to choose hamburger for lunch?

Answer 1

Mrs. Hinds can expect 480 students to choose hamburger for lunch.

Explanation:

Mrs. Hinds originally asks 30 students.
If she asks all 1200 students in the school, she would have to divide 1200 by 30.
1200 ÷ 30 = 40
Now she has to multiply 40 by how many students originally wanted hamburger.
40 × 12 = 480
Mrs. Hinds can expect 480 students to choose hamburger for lunch.
