Question

How to make 3/10 a percent?

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 now write and solve this equation for `x`:

`x/100 = 3/10`

`color(red)(100) xx x/100 = color(red)(100) xx 3/10`

`cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100))) = 300/10`

`x = 30`

`3/10 = 30%`

Answer 2

`30%`

Explanation:

A percent is a value given out of `100`

One method of changing a fraction to a decimal is to find an equivalent fraction with `100` as the denominator.

`3/10 xx 10/10 = 30/100`

`=30%`
