If you need subtracting 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 17.45 − 11.77 and 47.82 − 9.93 on the printed page, with 5.68 and 37.89 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 is where place-value understanding gets tested. To a child who really understands 67.48 − 1.72, the tenths column is not 'the first column after the point' — it is a place worth a tenth.
Writing in a trailing zero so both numbers have the same number of decimal places is not required mathematically and helps enormously in practice.
Estimation is the check that works best here. Rounding each number in 47.82 − 9.93 to the nearest whole gives a total that 37.89 has to be close to.
Adding decimals is column addition with one extra rule: the decimal points line up. Get that right and 17.45 − 11.77 is no harder than the whole-number version; get it wrong and the answer is not remotely 5.68.
In US classrooms these subtracting decimals worksheets are commonly aligned with the decimal operations expectations for grade 5, though the exact wording varies from state to state.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 17.45 − 11.77 = | 5.68 | Watch for: treating the two sides of the point as separate numbers |
| 2 | 47.82 − 9.93 = | 37.89 | Check: not estimating |
| 3 | 67.48 − 1.72 = | 65.76 | Look at: regrouping across the decimal point incorrectly |
| 4 | 94.23 − 34.62 = | 59.61 | Ask about: lining the numbers up on the right |
| 5 | 56.42 − 16.57 = | 39.85 | Watch for: losing the decimal point in the answer |
| 6 | 13.87 − 5.84 = | 8.03 | Check: forgetting the trailing zero |
A good first problem to do together is 17.45 − 11.77, which comes out at 5.68. Do 17.45 − 11.77 once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.
Try 67.48 − 1.72 together before letting the child start alone. The answer to 67.48 − 1.72 is 65.76, and talking through how it was reached takes about a minute and saves several minutes of guessing later in the sheet.
Because the numbers are random, there is no shared answer list to look up: the key printed behind your sheet is the only one that fits it, and it shows 5.68 for 17.45 − 11.77.
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.
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.
For a class set, print one sheet, press the new-worksheet button and print again. Each child gets different numbers on the same skill, so nobody can copy the answer to 17.45 − 11.77 from a neighbour.
