$1/20$

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:

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