If you need multiplying decimals worksheets that you can print right now, this page builds them for you — 20 fresh problems, an answer key underneath, and no account to create first. You will see items like 7.6 × 6 and 3.9 × 9 on the printed page, with 45.6 and 35.1 waiting on the answer key so nobody has to redo the arithmetic.
‘New set of problems’ opens the generator in its own tab. There you can change the problem count and turn the answer key on or off. ‘Print or save as PDF’ opens the print dialog — choose Save as PDF in the printer list to keep the file. The sheet fits US Letter and A4, and the answer key prints on its own page.
This sheet uses a one-place decimal times a whole number, which keeps the whole-number multiplication manageable while still requiring correct placement.
Unlike addition, the points do not need to line up here — which surprises children who have just learned the opposite rule for adding.
Estimation catches the placement errors that the method cannot. A rough version of 3.9 × 9 tells you within a factor of ten where 35.1 must land.
The count is simply the total number of decimal places in the two factors. Children who understand that never have to guess where the point goes.
In US classrooms these multiplying decimals worksheets are commonly aligned with the decimal multiplication expectations for this grade, though the exact wording varies from state to state.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 7.6 × 6 = | 45.6 | Watch for: rounding the factors first |
| 2 | 3.9 × 9 = | 35.1 | Check: forgetting the point completely |
| 3 | 4.9 × 4 = | 19.6 | Look at: miscounting the decimal places |
| 4 | 4.6 × 2 = | 9.2 | Ask about: dropping a trailing zero before placing the point |
| 5 | 3.2 × 7 = | 22.4 | Watch for: lining up the decimal points |
| 6 | 9.8 × 2 = | 19.6 | Check: placing the point by eye |
Work 4.6 × 2 out loud as a demonstration. It gives 9.2. Children who hear 4.6 × 2 reasoned through once at the start of a session make noticeably fewer errors in the ten minutes that follow.
Try 4.9 × 4 together before letting the child start alone. The answer to 4.9 × 4 is 19.6, and talking through how it was reached takes about a minute and saves several minutes of guessing later in the sheet.
Keys are produced by the same code that produces the questions, so a mismatch between question and answer is not possible on these sheets.
Every generated sheet carries its own key on a separate printed page, which lets a child self-mark without seeing the answers while they work.
Portrait orientation is what the sheet is designed for. Landscape works but wastes about a third of the paper, so leave the orientation alone unless you have a reason.
Printing works the same on US Letter and A4, because the layout uses relative widths rather than fixed inches. Set margins to default and scaling to 100%, and all 20 problems fit.
Keep the finished multiplying decimals worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
