Question

16% of what number is 192?

Answer 1

16% of 1200 = 192

Explanation:

If you are writing about percentage you use the form `16%`

If you are calculating using percentage you use the form `16/100`

Let the unknown value be `x`

Then

`16/100xx x =192`

Multiply both sides by `color(blue)(100/16)` to get `x` on its own

`color(brown)(16/100color(blue)(xx100/16) xx x= 192 color(blue)(xx 100/16))`

But `16/100xx100/16 -> 16/16xx100/100 = 1xx 1 =1` giving

`x=(192xx100)/16= 1200`
