Question

How do you write 80% as a fraction?

Answer 1

`80%=80/100=8/10 =4/5`

Answer 2

`4/5`

Explanation:

`80%` is the same thing as `80` out of `100`, which can be written as a fraction as `80/100`.

However, this can still be simplified, Since both of them are still divisible number. That number we want to divide both numerator and denominator by is called the GCF , or Greatest Common Factor .

First, let's list out the factors of `color(blue)80`:
`1, 2, 4, 5, 8, 10, 16, 20, 40, 80`

Now the factors of `color(blue)100`:
`1, 2, 4, 5, 10, 20, 25, 50, 100`

Now we find the largest factor of both numbers. That factor is `color(blue)20`.

So we divide both numerator by `color(blue)20`:
`80/100 color(blue)(-: 20/20)`

Which equals:
`4/5`

Hope this helps!
