Question

How do you write `1/8` as a decimal?

Answer 1

`1/8=0.125`

Explanation:

First remember that `8=2 times 4`

and `4=2 times 2`

then `8=2 times 2 times 2`

So, `1/8=1/(2 times 2 times 2)=1/2 times 1/2 times 1/2`

And recall that `1/2` of something is `50%` of that same something

Therefore, `1/8` of something is `1/2` of `1/2` of `50%` of that something

`1/2` of `50` is `25`

and `1/2` of `25` is `12.5`

So `1/8` is the same as `12.5%`

and since a percentage is the same as a decimal `times 100`

We have `1/8=0.125`
