Practice Fraction Operations
Master adding and subtracting fractions with unlike denominators, multiplying fractions, and dividing fractions.
In fifth grade, fraction operations become truly complex: adding and subtracting fractions with unlike denominators, multiplying fractions, and dividing fractions. This is the foundation for ratios, proportions, and algebra. A child who does not understand fraction operations in fifth grade will struggle significantly in middle school math.
Our fraction worksheets use visual models extensively and progress from like denominators to unlike denominators, from simple multiplication to division. The fifth grade math hub offers more resources for a complete curriculum.

For 1/3 + 1/4, find LCM of 3 and 4 = 12. Convert: 1/3 = 4/12, 1/4 = 3/12. Add: 4/12 + 3/12 = 7/12.
Multiply numerators, multiply denominators: 2/3 × 3/4 = 6/12 = 1/2. For mixed numbers, convert to improper fractions first.
For division: Keep the first fraction, change ÷ to ×, flip the second fraction. 2/3 ÷ 3/4 = 2/3 × 4/3 = 8/9.
Adding and subtracting fractions with like denominators. Review and reinforcement.
Adding and subtracting fractions with unlike denominators. Introduces finding common denominators.
Multiplying and dividing fractions with mixed numbers and word problems. For end-of-year mastery.
For some children, the gap is not in practice — it is in the conceptual foundation that makes fraction operations make sense. If your child cannot explain why finding a common denominator works or why multiplying fractions is different from adding them, worksheets alone will not bridge that gap. Our Fractions and Decimals Foundations course (grades 4-6) covers the full progression from fraction basics through operations with fractions and decimals. You can also browse all available courses and planners on the resources page.

By the end of fifth grade, students should add and subtract fractions with unlike denominators, multiply fractions (including mixed numbers), divide fractions by whole numbers and whole numbers by fractions, and solve fraction word problems.
Step 1: Find a common denominator (often the least common multiple). Step 2: Convert both fractions. Step 3: Add the numerators, keep the denominator. Step 4: Simplify. Use visual models: fraction bars showing 1/2 = 2/4, 1/4 + 2/4 = 3/4.
Multiply numerators, multiply denominators: 2/3 × 3/4 = 6/12 = 1/2. Use visual models: a rectangle divided into thirds one way and fourths the other way shows the product area. For fraction times whole number: 2/3 × 12 means 2/3 of 12 = 8.
Teach "Keep, Change, Flip": Keep the first fraction, change division to multiplication, flip the second fraction. 2/3 ÷ 3/4 = 2/3 × 4/3 = 8/9. Use visual models: how many 3/4 are in 2/3? The answer is less than 1.
10-12 fraction problems per day is enough. Mix types: adding/subtracting unlike denominators, multiplying, dividing, and word problems. Use visual models regularly.
Mastery means your child can: 1) add and subtract fractions with unlike denominators, 2) multiply fractions and mixed numbers, 3) divide fractions, 4) solve fraction word problems, and 5) explain the procedures using visual models.
