Question

At a school, 60% of the sixth-grade students said that pizza is their favorite kind food. If 210 sixth-grade students prefer pizza, how many sixth-grade students are at the school?

Answer 1

350

Explanation:

Let
`s=` total number of sixth-grade students.

It is given that 60% of sixth-grade students prefer pizza which is equivalent to 210 sixth-grade students. With this, the following can be written:

`60\%s = 210`

`0.6s=210` (
`60\%` can be converted into the decimal form
`0.6`)

`s = 210/ 0.6`

`=350`

∴ There is a total of 350 sixth-grade students in the school.

Hope this helps :)
