Question

If Orlando missed 5 out of 40 questions on the test, what percent of the questions did he get right?

Answer 1

`color(green)(87.5%)`

Explanation:

Orlando got `40-5=35` out of `40` right.

That is he got `35/40` right.

As a percentage:
`color(white)("XXX")35/40=35/cancel(40)_2xxcancel(100)^5/color(red)(100)`

`color(white)("XXXXX")=(175/2)/color(red)(100)`

`color(white)("XXXXX")=87.5/color(red)(100)`

`color(white)("XXXXX")=87.5 "per 100"`

`color(white)("XXXXX")=87.5%` (since "per cent" means "per humdred")
