Subtraction of Mixed Numbers is a Grade 8 mathematics worksheet that gives students 10 multiple-choice problems involving mixed numbers and whole numbers. Students find differences such as 5 1/2 − 3 and 12 1/4 − 5, then subtract mixed numbers with like or related fractional parts, including examples such as 8 2/3 − 4 1/3 and 6 3/4 − 2 1/2. The set also includes problems that require regrouping, such as subtracting 3 3/4 from 9 1/4. This free printable worksheet helps students apply accurate procedures for subtracting the whole-number and fractional parts of mixed numbers, convert fractional parts when needed, and identify a correct result from several choices. It is suitable for Grade 8 independent practice, guided review, or a quick check of computational fluency. A complete answer key is included so teachers can verify responses efficiently and address errors in fraction subtraction or regrouping.

This Grade 8 worksheet covers subtracting whole numbers from mixed numbers and subtracting one mixed number from another through 10 multiple-choice questions. Students calculate differences such as 7 3/4 − 2, align equivalent fractional parts when needed, and use regrouping in examples such as 9 1/4 − 3 3/4.
Model one item that subtracts a whole number from a mixed number, then show how to rewrite a fraction with an equivalent denominator before solving a mixed-number subtraction problem. Use the multiple-choice options to ask students which step produced each distractor, especially when a problem requires regrouping, such as 9 1/4 − 3 3/4. After guided examples, have students complete the remaining questions independently and explain one solution.
Watch for students subtracting fractional parts with unlike denominators without rewriting them, treating a mixed number as a single whole number, or reversing the subtraction order. On regrouping items such as 9 1/4 − 3 3/4, students may fail to rename one whole as fourths and choose an answer based on subtracting 3/4 from 1/4 directly. The multiple-choice distractors make these calculation errors easier to identify and discuss.
You can assign this worksheet as a printable PDF or as a digital quiz on Wayground. It includes a complete answer key for all 10 multiple-choice questions, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format also supports classrooms that are reducing screen time.
In the worksheet’s Advanced Settings, adjust font spacing or choose a larger font size so the mixed-number expressions and multiple-choice options are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language, depending on your students’ needs.
