Let's multiply these decimal numbers

We'll start by multiplying the base numbers. 4 times 8 gives us 32

Now we need to count the decimal places. 0.04 is 2 decimal places smaller than 4. 0.8 is one decimal place smaller than 8.

We can move the decimal in 32 by both of these amounts, so we end up with 0.032 as our answer.
