Answer:
Step-by-step explanation:
Well, since a 0.45 certainly equals 45/100, we'll start there and then simplify
Each number is divisible by 5, so let's divide each side by 5
[tex]\frac{45}{5} = 9\\\frac{100}{5} = 20[/tex]
Putting each of those numbers in correct places we get: 9/20
➜Simplest form: [tex]\frac{9}{20}[/tex]
I'm always happy to help :)
