Each problem subtracts two fractions that already have the same denominator, such as 7/10 − 3/10. Students subtract the numerators, keep the common denominator and simplify the result. The first fraction is always at least as large as the second, so answers are never negative.

This is the most direct form of fraction subtraction and lets students focus on the meaning of like-sized parts. The answer key reduces every result to lowest terms and shows whole-number answers as whole numbers.

When to use it

Use this page after students understand equivalent fractions and can add fractions with a common denominator. It fits a first lesson on fraction subtraction, independent practice after using fraction strips, or review before unlike denominators are introduced.

Teaching tips

  • Read the units aloud: seven tenths minus three tenths leaves four tenths.
  • Use a fraction strip or shaded bar to show that the denominator names the size of each part and does not change.
  • Address the common mistake of subtracting both denominators by comparing it with subtracting named objects.
  • Make simplifying a separate final check: find a common factor in the numerator and denominator.
  • Ask students to estimate whether an answer should be close to zero, one half or one whole before calculating.

How to print this worksheet

  1. Check the settings above. They are already set for subtracting fractions with the same denominator.
  2. Pick 10, 15, 20 or 30 problems, a title, and the name or date lines you want.
  3. Choose US Letter or A4 to match the paper in your printer.
  4. Press Download PDF for a file you can save and reuse, or Print to send it straight to your printer.
  5. Keep the answer key page for yourself. The sheet number in the footer lets you make the exact same sheet again later.

What comes next

Mix addition and subtraction with like denominators once both operations are secure. The next major step is subtraction with unlike denominators, where students first use equivalent fractions to create a common denominator.

Frequently asked questions

Do the denominators change when subtracting?
No. When the denominators already match, subtract the numerators and keep that shared denominator, then simplify the result if possible.
Can an answer be negative?
No. The generator always makes the first fraction greater than or equal to the second fraction.
Are the answers simplified?
Yes. For example, 6/8 − 2/8 is shown as 1/2 rather than 4/8, and a result such as 5/5 is shown as 1.

Worksheets are generated automatically and checked by automated tests, but please review each sheet before using it in class.
