Teaching tips and what to try next

This belongs late in fifth grade, after students can multiply simple fractions and switch between mixed numbers and improper fractions. Ask for a quick estimate before each problem; an answer far from the estimate usually means a conversion slipped. Review Multiplying Fractions or Improper Fractions and Mixed Numbers, and for the next step try Dividing Unit Fractions and Whole Numbers.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

Fifth graders use fraction multiplication to solve real problems, like making 2 1/2 batches of a recipe that calls for 1 3/4 cups of flour. That means multiplying mixed numbers. This fifth-grade worksheet gives twelve mixed number multiplication problems that build in difficulty.

Four problems multiply a mixed number by a whole number, such as 2 1/3 × 4. Four multiply a mixed number by a fraction, such as 3 1/2 × 2/5. The last four multiply two mixed numbers, such as 1 2/3 × 2 1/4. Every fraction on the page is in simplest form, with denominators from 2 to 6, and the problems are mixed together so students must read each one carefully. Answers are written in simplest form: a whole number, a mixed number, or a fraction less than 1. Each of the ten versions uses new numbers.

How to use it: the most reliable method is to change each mixed number to an improper fraction, multiply the numerators and the denominators, and then simplify. Remind students that 2 1/3 becomes 7/3 because 2 × 3 + 1 = 7. A common mistake is to multiply the whole numbers and the fractions separately, which gives the wrong answer; try 1 1/2 × 1 1/2 both ways to show why. Estimating first also helps: 1 2/3 × 2 1/4 should be a little less than 2 × 2. Students can simplify before multiplying by canceling common factors.

The answer key lists every product in simplest form. This worksheet supports Common Core standard 5.NF.B.6. Review the basics with our Multiplying Fractions worksheet and our Improper Fractions and Mixed Numbers worksheet.
