Decimal multiplication worksheets teach one reliable method: multiply the numbers as if they were whole numbers, then place the decimal point by counting the decimal places in both factors. These free printable multiplying decimals worksheets go from decimals times whole numbers to tenths, hundredths and powers of ten, with an answer key on every PDF and a maker for new problems.
Quick answer: To multiply decimals, ignore the decimal points and multiply as whole numbers, then count the decimal places in both factors and put that many places in the product: 0.6 × 0.4 = 0.24. This page has 8 free decimal multiplication worksheets (PDF) with answer keys for grades 5 and 6, plus a maker for new problems. Updated October 2026.

How to multiply decimals in three steps
Multiply as whole numbers: ignore the decimal points, so 0.6 × 0.4 becomes 6 × 4 = 24.
Count the decimal places in both factors: 0.6 has one place and 0.4 has one place, so two in all.
Place the decimal point so the product has that many places: 0.24.
Unlike adding decimals, you do not line up the decimal points. The method works because tenths times tenths are hundredths.

Multiplying decimals by 10, 100 and 1,000
Multiplying by a power of ten just moves the decimal point to the right, one place for each zero. This is a shortcut that fifth graders should know well:

Estimate first: does the answer make sense?
Rounding the factors gives a quick check on the placement of the decimal point. If the estimate and the exact answer are close, the point is in the right place:

Multiplying decimals by whole numbers worksheet
A decimal times a whole number is the easiest case: multiply as whole numbers, then count the decimal places in the decimal factor only. For 1.25 × 4, 125 × 4 = 500, and two places gives 5.00, which is 5. The first sheets above start here, with money and measurement problems as examples.

Lining up the decimal points
0.6 × 0.4: lining up points like addition
Multiplication does not need aligned points: multiply as whole numbers, then place the point
Counting the places in only one factor
0.6 × 0.4 = 2.4
Count the places in both factors: two places, so 0.24
Dropping a zero
0.5 × 0.3 = 0.015
5 × 3 = 15, with two places gives 0.15
Moving the point the wrong way
0.45 × 10 = 0.045
Multiplying by 10 moves the point one place right: 4.5

Why the decimal point goes where it does
A tenth of a tenth is a hundredth, which is why 0.1 × 0.1 = 0.01. Each decimal place divides by 10, so two factors with one place each give a product with two places. This is the reason for counting the places in both factors, and why 0.6 × 0.4 = 0.24 and not 2.4.
Sometimes the product needs a zero placeholder. In 0.08 × 0.9, 8 × 9 = 72 and there are three decimal places, so the answer is 0.072, with a zero added before the 7. Remind students that a product with three places must show three digits after the point.

Tips for teachers and parents
Use a hundred grid to show 0.4 × 0.6: shade 4 tenths across and 6 tenths down, and the overlap is 24 of 100 squares, so 0.24. Pair the grid with the whole-number method so students see the two ideas match.
Encourage estimation every time. If 4.8 × 3.2 is close to 5 × 3 = 15, then an answer of 1.536 or 153.6 is clearly wrong. This quick check does more to prevent decimal point errors than any rule. Review the place value chart page if place value is still shaky.
Which decimal multiplication worksheet should you start with?
Start with decimals times whole numbers, since the decimal point rule is easiest there. Move to tenths and hundredths when students can explain where the point goes. Set B can be used a week later.

How do you multiply decimals?
Multiply the numbers as whole numbers, count the decimal places in both factors, and put that many places in the product. For example, 0.6 × 0.4 = 0.24.
Do you line up the decimal points when you multiply?
No. Lining up decimal points is for adding and subtracting. For multiplication, multiply as whole numbers and then place the point.
How do you multiply a decimal by 10?
Move the decimal point one place to the right. Multiplying by 100 moves it two places, and by 1,000 three places.
What grade multiplies decimals?
Grade 5 multiplies decimals to hundredths, and grade 6 extends this to multi-digit decimals.
