Fractions to Decimals Worksheets

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.

📄 FRACTIONS TO DECIMALS WORKSHEETS — A NEW SHEET EVERY TIME YOU PRESS THE BUTTON
🎲 New set of problems

‘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.

What these worksheets cover

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.

Six problems from the sheet in front of you

These six come from the sheet loaded on this page. Press the button and the numbers change, but the shape stays the same (denominators of 2, 4, 5, 8, 10, 20 and 25).
#ProblemAnswerWhat to check
12/10 as a decimal =0.2Watch for: finding the percentage of the wrong quantity
210/20 as a decimal =0.5Check: adding percentages of different wholes
32/8 as a decimal =0.25Look at: moving the decimal point the wrong way
41/2 as a decimal =0.5Ask about: treating the percentage as a plain number
523/25 as a decimal =0.92Watch for: rounding money percentages badly
65/8 as a decimal =0.625Check: confusing a percentage increase with the resulting value

Try one together first

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 three errors worth watching for

Using this sheet as a daily drill

  1. Run the sheet at the same time each day. Ten focused minutes before dinner beats an hour on Sunday, because converting fractions to decimals is a recall skill: 2/10 as a decimal has to arrive without being worked out, and recall is built by frequency.
  2. If two days in a row come out under 10 minutes with everything correct, that is the signal to move up: either numbers bigger than 2/10 as a decimal uses, or the next skill in the sequence.
  3. Use a pencil, not a pen. Children working on converting fractions to decimals rethink far more often when erasing is allowed, and you get to see exactly where the rethinking happened on an item like 2/8 as a decimal.
  4. Re-print the same skill rather than the same sheet. Because the numbers change, a child who memorised that 2/10 as a decimal gives 0.2 still has to actually calculate tomorrow.
  5. Stop the session at the time limit even if the sheet is unfinished, and note where the child got to. A half sheet done well is better data than a whole sheet rushed.

The answer key

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.

Printing on US Letter or A4

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.

Frequently asked questions

Do percentages need to be converted to decimals?
For written calculation it is usually easiest, yes. For mental work the benchmark method is faster and less error-prone.
What is the fastest way to find a percentage mentally?
Find ten per cent by dividing by ten, then build the rest from it. Twenty is double, five is half, one per cent is a tenth of the ten per cent.
Are these worksheets really free?
Yes, completely. The page is supported by advertising, not by subscriptions, so there is no limit on how many fractions to decimals worksheets you print.
Can I change how many problems are on the page?
Yes — the generator takes 10, 20 or 30 problems. Twenty is the default because it fits one page and suits a 10-minute drill.

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.
