A worksheet on multiplying fractions. The exercises require to find the missing numbers in given calculations. Answers are included.

Master fraction operations and algebraic thinking with this 4-page missing fraction worksheet pack. Ideal for Year 5, Year 6, and Key Stage 2 maths revision.

Help your students move past standard computation and build deep conceptual fluency with this printable Multiplying Fractions with Missing Numbers Worksheet Pack. Instead of simply multiplying straight across, these questions leave strategic blanks in the numerators, denominators, or final reduced products—forcing students to apply inverse operations, analyze cross-simplification, and use equivalent fractions to solve the puzzle.
This resource contains 2 student practice worksheets featuring 24 carefully scaffolded problems and 2 complete answer key pages—fully worked out to save you valuable marking time or to allow for student self-assessment!

Why Focus on Missing Numbers in Fractions?
Solving for missing numerators or denominators in multiplication requires a firm grasp of cross-simplification and fraction reduction. By transitioning students progressively from straightforward equations (such as 2/3 x 1/5 = 2/[ ]) to advanced problems where finding the missing number requires identifying canceled-out common factors (such as 1/9 x [ ]/4 = 1/4, where the missing value is 9), they internalize how fractions balance out structurally.

What’s Included in This Resource?
• Scaffolded Skill Progression: The packet begins on Worksheet 1 with straightforward missing products and clear missing numerators or denominators. It advances on Worksheet 2 to advanced problems where finding the missing number requires identifying cross-simplification or balancing whole fraction blocks (such as [ ]/12 x 1/2 = 1/3).
• Cross-Simplification & Reduction Fluency: Many equations result in fully simplified final products. This pushes students to critically analyze how common factors are canceled out before arriving at a final, simplified fraction.
• Algebra Readiness: Working backward to find a missing part of a fraction provides excellent foundational preparation for solving multi-step variable equations in secondary school.
• Pages 3–4: Step-by-Step Answer Keys: Includes full solutions and answers clearly boxed and filled in for every single question to encourage independent self-marking or quick teacher grading.

Curriculum and Age Suitability
• Primary (KS2 / Year 5 & Year 6): Highly relevant for Upper Key Stage 2 students mastering multiplying proper fractions, generating equivalent fractions, and writing final answers in their simplest form.
• Secondary (KS3 / Year 7): Excellent as a diagnostic tool, math intervention group resource, or formal arithmetic revision.
• Adaptable Format: Perfect for whole-class lessons, independent desk work, secondary extensions, homework assignments, or structured test prep.
