How do I show on a hundred grid what 18% of 520 is? I know what the answer is but don't know how the grid can help me find the answer and that is what the teacher wants us to show. Thanks in advance!

.18 x 520 = 93.6 <~~right?

100 - 93.6 = 6.4

So ... on a 100-square grid, you'd darken 6 squares and just under half of the 7th square.

Right??
