Question #acb4b

Answer 1

"Percent" or "%" means "out of 100" or "per 100".

`x/100 = 9/25`

Explanation:

"Percent" or "%" means "out of 100" or "per 100".

So we can solve:

`x/100 = 9/25`

`color(red)(100) xx x/100 = color(red)(100) xx 9/25`

`cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100))) = cancel(color(red)(100))4 xx 9/color(red)(cancel(color(black)(25)))`

`x = 36`

`36%` of the students are home sick.

Another way to solve is:

`x/100 = 9/25`

`x/100 = color(red)(4)/color(red)(4) xx 9/25`

`x/100 = 36/100`

`x = 36`
