Multiplying decimals may look tricky, but it's quite simple if you know how to multiply whole numbers. You can multiply numbers with decimals just as you would multiply whole numbers, as long as you remember to factor in the decimals at the end of the problem. So how do you do it? Follow these steps to find out.

**1: Line up the numbers on top of each other.**If one number has more digits, you can put the number on top of the other. Let's say you're multiplying .43 by .06. Just line one number on top of the other.

**2: Multiply the numbers - ignoring the decimal points.**Now, just multiply the numbers as you usually would in ordinary multiplication. Here's how you would multiply .43 and .06:

- Start by multiplying the 6 in .06 by the 3 in .43 to get 18. Write "8" below the 6 and carry the 1 on top of the 4.
- Multiply the 6 by the 4 in .43 to get 24. Add 24 to the 1 that was on top of the 4 to get 25. The top row should read 258.
- When you start multiplying .43 by 0, you'll see that you only get 0, so there's no need to write anything down.
- The answer is 258 while you're ignoring the decimal points.

**3: Count up all of the number of numbers to the right of both decimal points.**There are two numbers to the right of .43 (4 and 3), and there are two numbers to the right of .06 (0 and 6). Therefore, add 2 and 2 to get 4, the total amount of numbers to the right of both decimal points.

**4: Move the decimal point of the whole number to the left that number of times.**Since you counted 4 numbers, start with the decimal point at the end of the whole number 258, and move it over four times to the left starting to the right of the 8. You'll end up moving it one space left past the 2 in 258.

**5: Fill in the extra space with a zero.**Since there's a blank space between the decimal point at the 2, fill it in with a zero. 258 becomes ".0258."
