$1.8$ $1.8$

We have the following:

$\frac{9}{5}$ $9/5$

We want to make the denominator $100$ $100$ , so we can multiply the top and bottom by $20$ $20$ . We now have

$\frac{180}{100}$ $180/100$

Dividing by $100$ $100$ is the same as looping the decimal two times to the left.

If we loop the decimal in $180$ $180$ to the left twice, we get $1.8$ $1.8$ . This is the same as $\frac{9}{5}$ $9/5$ .

Hope this helps!
