What fraction is represented by the portion of the figure that is not shaded? (2 out of 10 are shaded)
optional answers:
8/10
2/100
10/10
1/10

Well let's see.

If the figure is split up into 10 pieces, then
each piece is  1/10  of the whole figure.

If  2  of the pieces are shaded, then
2/10  of the whole figure is shaded.

How many pieces are left ?

There were 10 pieces all together, and
2 of them are shaded.  Hmmm.  I think
there are probably  (10 - 2) = 8  of them left
that are not shaded.

8 pieces makes  8/10  of the whole figure.

let me think hold on
