Question

What is 1.2 divided by 24?

Answer 1

`1/20`

Explanation:

We have

`1.2-:24`

Which can be expressed as a fraction:

`1.2/24`

Firstly, we should try go get rid of the decimal. To do this, multiply the fraction by `10//10`:

`1.2/24xx10/10=12/240`

Now, realize that `240=12xx20`:

`12/240=12/(12xx20)`

The `12`s will cancel:

`color(red)(cancel(color(black)(12)))/(color(red)(cancel(color(black)(12)))xx20)=color(blue)(1/20`
