5.4
"of" means "times" in math so 20 percent OF 27 is 0.2 x 27
This is correct, and a lot quicker than my method, but I'll give it to you anyway.
I use proportions.
First percent means "out of 100" so:
20/100
Then you have of 27. So 27 would become a denominator:
x/27
You now have:
20/100 x/27
and you cross multiply, getting 540 and 100x.
You want x alone so you have x=.
Therefore, you divide 540 by 100 and get 5.4.
