$9/20 = 9 -: 20 = 0.45$

Another way to look at this is:

$9/20 = 9/20 xx 5/5 = (9 xx 5)/(20 xx 5) = 45/100 = 0.45$

0.45

$9-:20$

$=> 9/20$

Convert the denominator into powers of 2 and 5.

$=> 9/(2xx2xx5$

$=> 9/(2^2xx5^1$

Now multiply both numerator and denominator with 5 to make the powers of 2 and 5 equal.

$=> (9xx5)/(2^2xx5xx5$

$=> 45/(2^2xx5^2$

You can combine the bases with same powers

$=> 45/10^2$

$=> 45/100$

$=> 0.45$
