Multiplying Fractions (Fraction × Fraction) — Easy Worksheet 2
Grade 5 · Whoobee Name: ____________________ Date: __________
Answer each question. The same kind of product comes in different shapes. Write fractions in simplest form, as a mixed number if greater than 1.
How to solve
Multiply the numerators, then multiply the denominators: 23 × 45 = 815. Simplify the answer, or cancel first: in 34 × 29 the 3 and 9 share 3 and the 2 and 4 share 2, so it becomes 12 × 13 = 16. Change mixed numbers to improper fractions before multiplying (1 12 = 32), and write an answer greater than 1 as a mixed number.
Example
16 × 16 = ___
Answer: 136
Warm-up
Not quite. The answer is
💡 Multiply the numerators: 4 × 1 = 4. Multiply the denominators: 5 × 7 = 35. That gives 435. 435 is already in simplest form.
✓ Correct!

💡 Work backwards: the missing number is 421 ÷ 47. To divide by 47, flip it to 74 and multiply: 421 × 74. Multiply the numerators: 4 × 7 = 28. Multiply the denominators: 21 × 4 = 84. That gives 2884. Simplify: divide the top and the bottom by 28: 2884 = 13. Check: 47 × 13 = 421. The missing number is 13.
