**Area models** can be used to find the product of two decimals.

In a 10 by 10 grid, an entire row or column represents 0.1,

and one square represents 0.01.

First, shade across the top 8 rows to represent 0.8.

Next, shade down the first column on the left to represent 0.1.

The overlapping area represents the product.

There are 8 shaded squares in the overlapping area.

So, 0.8 × 0.1 = 0.08.

Multiplying 0.03 by 7 is the same as adding 0.03 seven times.

Each tick on the number line represents 0.01, so 0.03 can be represented by jumping 3 ticks.

Represent the product by starting at 0 and jumping 3 ticks seven times.

So, 0.03 × 7 = 0.21.
