Every sheet of fractions to decimals 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. Right now the generator is set to problems such as 2/10 as a decimal (answer 0.2) and 10/20 as a decimal (answer 0.5); press the button again and the numbers change while the skill stays the same.
‘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.
Percentages, decimals and fractions are three notations for one idea, and switching between them fluently is what makes the whole topic feel small.
This sheet uses denominators of 2, 4, 5, 8, 10, 20 and 25, chosen so that the arithmetic can be done mentally by a child who knows the benchmark percentages, which is why a line such as 23/25 as a decimal turns up.
Ten per cent is the pivot: divide by ten, then build. Twenty per cent is double it, five per cent is half of it, fifteen per cent is one of each. That method handles 10/20 as a decimal and most everyday percentage work without a calculator.
A percentage is a fraction with a denominator of one hundred, and every percentage problem is a fraction problem underneath. Finding 2/10 as a decimal means taking that many hundredths of the number, which gives 0.2.
These fractions to decimals worksheets are commonly aligned with the ratio and proportional relationships strand for grade 6, and the skill appears in most curricula somewhere around this point.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 2/10 as a decimal = | 0.2 | Watch for: finding the percentage of the wrong quantity |
| 2 | 10/20 as a decimal = | 0.5 | Check: adding percentages of different wholes |
| 3 | 2/8 as a decimal = | 0.25 | Look at: moving the decimal point the wrong way |
| 4 | 1/2 as a decimal = | 0.5 | Ask about: treating the percentage as a plain number |
| 5 | 23/25 as a decimal = | 0.92 | Watch for: rounding money percentages badly |
| 6 | 5/8 as a decimal = | 0.625 | Check: confusing a percentage increase with the resulting value |
Take the first problem on the sheet as it stands, 2/10 as a decimal. Work 2/10 as a decimal out on paper rather than in your head the first few times, say each step aloud, and check the result against 0.2 on the key before moving on.
The item 10/20 as a decimal is worth doing slowly. The answer to 10/20 as a decimal is 0.5, and the route to it is the route every other problem on this sheet takes — which is why the sheet has 20 of them rather than one.
The key prints on its own page by default. Uncheck the answer-key box before printing if you would rather keep it back and mark the sheet yourself.
Keys are produced by the same code that produces the questions, so a mismatch between question and answer is not possible on these sheets.
The sheet is laid out to fit one page on both US Letter and A4. Leave the browser scaling at 100% and turn headers and footers off, and the 20 problems land inside the margins on either paper size.
If the problems look cramped, drop the count from 20 to a smaller number before printing these fractions to decimals worksheets; the font stays the same size and the spacing opens up.
Keep the finished fractions to decimals worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
