solution

In the model, the big square represents one whole. Since there are 10 total columns, the 6 shaded columns represent 6 tenths of the whole, or 0.6.

Within those shaded columns, 4 of the 10 rows are shaded again. This double-shaded region represents 4 tenths of 0.6, or

0.4

0.6

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

0.4

0.6

Notice that the double-shaded region is made up of 24 small squares. Since there are 100 small squares in the whole, this represents 24 hundredths, or 0.24.
