Question

40 inches is what percent of 28 inches?

Answer 1

See a solution process below:

Explanation:

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

We can then write and solve for `x`:

`40/28 = x/100`

`color(red)(100) xx 40/28 = color(red)(100) xx x/100`

`4000/28 = cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100)))`

`142.86 ~= x`

40 inches is approximately `142.86%` of 28 inches
