Hey there! :D
So, what we need to do is make a fraction that has a denominator of 100. This is the simplest route to take.
330/500
If you took one zero away from each side, you will get an equivalent fraction:
33/50
Multiply both side by 2 to get to 100.
33*2=66 50*2=100
66/100
So, 66% percent ornament the parking lots were filled.
I hope this helps!
