Question #d8e9f

Answer 1

See the entire solution process below:

Explanation:

"Percent" or "%" means "out of 100" or "per 100", Therefore 15% can be written as `15/100`.

So we can write and solve this equation:

`15/100 = 1868/p`

`(color(red)(100)color(green)(p))/color(blue)(15) * 15/100 = (color(red)(100)color(green)(p))/color(blue)(15) * 1868/p`

`(cancel(color(red)(100))color(green)(p))/cancel(color(blue)(15)) * color(blue)(cancel(color(black)(15)))/color(red)(cancel(color(black)(100))) = (color(red)(100)cancel(color(green)(p)))/color(blue)(15) * 1868/color(green)(cancel(color(black)(p)))`

`p = 186800/15`

`p = 12453.bar3`

1,868 is 15% of `color(red)(12,453.bar3`
