Every sheet of 6th grade percentage of a number worksheets on this page is built the moment you open it, so the 20 problems below are not the same ones the last visitor printed, and the answer key is generated with them. You will see items like 10% of 150 and 25% of 30 on the printed page, with 15 and 7.5 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.
Because the numbers regenerate, the child practises the method rather than recognising familiar percentages.
This sheet uses percentages of numbers up to 200, chosen so that the arithmetic can be done mentally by a child who knows the benchmark percentages, which is why a line such as 5% of 130 turns up.
Percentages, decimals and fractions are three notations for one idea, and switching between them fluently is what makes the whole topic feel small.
A percentage is a fraction with a denominator of one hundred, and every percentage problem is a fraction problem underneath. Finding 10% of 150 means taking that many hundredths of the number, which gives 15.
Teachers usually place 6th grade percentage of a number worksheets alongside the ratio and proportional relationships strand for grade 6, which is where the skill sits in the majority of US state frameworks.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 10% of 150 = | 15 | Watch for: moving the decimal point the wrong way |
| 2 | 25% of 30 = | 7.5 | Check: finding the percentage of the wrong quantity |
| 3 | 50% of 30 = | 15 | Look at: confusing a percentage increase with the resulting value |
| 4 | 75% of 60 = | 45 | Ask about: adding percentages of different wholes |
| 5 | 5% of 130 = | 6.5 | Watch for: rounding money percentages badly |
| 6 | 60% of 190 = | 114 | Check: treating the percentage as a plain number |
A good first problem to do together is 10% of 150, which comes out at 15. Do 10% of 150 once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.
Take the first problem on the sheet as it stands, 10% of 150. Work 10% of 150 out on paper rather than in your head the first few times, say each step aloud, and check the result against 15 on the key before moving on.
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 15 for 10% of 150.
The answer key is generated with the worksheet, not written by hand, so it always matches the sheet in front of you — 10% of 150 is listed as 15, 25% of 30 as 7.5, and so on down the page.
To save these 6th grade percentage of a number worksheets instead of printing them, choose 'Save as PDF' in the printer list. You get the worksheet and the answer key as a single PDF, on Letter or A4 depending on your printer settings.
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 6th grade percentage of a number worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
