Question

Hampton Middle School is expecting 376 seventh-graders next year. This is 40% of the expected school enrollment. How many students are expected to enroll in the school next year?

Answer 1

I got `940`

Explanation:

Let us call the total number of sudents `x`; this corresponds to `100%` or the total number of stdents.
We can now relate the quantities with the percents as:
`(100%)/(40%)=x/376`
i.e. in "percent world" you have `40` out of `100` students while the corresponding in "students world" will be `376` out o`x` (the total).
Rearranging:
`x=(100cancel(%))/(40cancel(%))*376=940` students in total.

Hope it helps!
