What percent of 120 is 66?

So on my paper.. I wrote 120 out of 100, because all percents add up to be 100 percent.
And then I wrote = 66 over x.
Is this correct?
and then I would do the butterfly method? ( Cross Multiply)
Thank you!

yes, that will work.

personally, I would just take
66/120 = .55 or 55%
Thank you.
