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!

Roots with imaginary parts always occur in conjugate pairs. Three of the four roots are known and they are all real, which means the fourth root must also be real.
Because we know 3 and -1 (multiplicity 2) are both roots, the last root 
is such that we can write
There are a few ways we can go about finding , but the easiest way would be to consider only the constant term in the expansion of the right hand side. We don't have to actually compute the expansion, because we know by properties of multiplication that the constant term will be 
.
Meanwhile, on the left hand side, we see the constant term is supposed to be 9, which means we have
so the missing root is 3.
Other things we could have tried that spring to mind:
- three rounds of division, dividing the quartic polynomial by 
, then by 
twice, and noting that the remainder upon each division should be 0
- rational root theorem
I csn help for the first one can't help with the colunms the answer is 1,396.
