solution

In the model, the big square represents one whole. Since there are 10 total columns, the 4 shaded columns represent 4 tenths of the whole, or 0.4.

Within those shaded columns, 2 of the 10 rows are shaded again. This double-shaded region represents 2 tenths of 0.4, or

0.2

0.4

So, you can look at the double-shaded region to find

0.2

0.4

Notice that the double-shaded region is made up of 8 small squares. Since there are 100 small squares in the whole, this represents 8 hundredths, or 0.08.
