Question

12 is what percent of 200?

Answer 1

`6%`

Explanation:

How? `12/200xx100%=6/100xx100%=6.0%`.

Answer 2

`6%`

Explanation:

First of all, per `cent` means per `hundred` or `/100`.
`:. x%` can be written as `x/100`.

Let 12 be `x%` of 200, where `x` can be any whole number(0 to infinity) or decimal number(numbers with a '`.`').

Then, `200 xx x% = 12`
`color(white)("XXX")` `200 xx x/100 = 12`
Multiplying both sides by `100/200`(in order to eliminate the numbers with `x`),
`x = 12 xx 100/200 = 12 xx (1cancel(00))/(2cancel(00)) = 12/2 = 6`
