Multiplying fractions worksheets
Multiply whole numbers by fractions, fractions by fractions, and improper fractions. Every answer in the key is in simplest form, written as a mixed number when it's more than one.
How to solve them
- Multiply the numerators.
- Multiply the denominators.
- Simplify: divide the top and bottom by their greatest common factor.
- If the top is bigger than the bottom, write it as a mixed number.
Ready-to-print multiplying fractions worksheets
Nine fixed sets — three per level. Each PDF has the problems followed by the answer key.
Levels
| Level | Problems | Grade |
|---|---|---|
| Easy | Whole number × fraction (4 × 2/3) | 4 |
| Medium | Proper fraction × proper fraction | 5 |
| Hard | Improper fractions with denominators to 12 | 5–6 |
A shortcut: cancel first
Before multiplying, look for a numerator and a denominator that share a factor. In 4/9 × 3/8, divide 4 and 8 by 4 and 3 and 9 by 3: the problem becomes 1/3 × 1/2 = 1/6, with no simplifying at the end.

Frequently asked questions
Are the answers simplified?
Yes. Every answer is in lowest terms, with improper results written as mixed numbers (for example 2 1/4) and whole-number results written as whole numbers.
How do you multiply a whole number by a fraction?
Write the whole number over 1 and multiply as usual: 3 × 2/5 = 3/1 × 2/5 = 6/5 = 1 1/5.
Is there an answer key?
Yes. The PDF always ends with an answer key for the same problems, so you can print the questions for students and keep the key. Every answer is checked by automated tests.
Can I print the same worksheet again later?
Yes. Every sheet has a set number (the seed) printed in the footer and saved in the page address. Open the same link, or type the same level, count and set number, and you get exactly the same problems and answer key.
