What You Will Learn
- Recognise proper and improper fractions.
- Understand mixed numbers using whole objects and fractional parts.
- Convert an improper fraction into a mixed number.
- Convert a mixed number into an improper fraction.
- Compare and simplify fraction forms.
1. Proper Fractions
A proper fraction has a numerator smaller than its denominator. Its value is less than one whole.
Three quarters means three out of four equal parts of one whole.
Examples include 1/2, 3/5 and 7/10.
2. Improper Fractions
An improper fraction has a numerator that is equal to or greater than its denominator. Its value is one whole or more.
- 5/4 is greater than one whole.
- 8/8 is exactly one whole.
- 9/4 is more than two wholes.
3. Mixed Numbers
A mixed number contains a whole number and a proper fraction. For example, 1 3/4 means one whole and three quarters.
One complete object plus three quarters of another same-sized object.
Mixed numbers are useful when describing measurements, recipes and quantities that are more than one whole.
4. Convert an Improper Fraction to a Mixed Number
Divide the numerator by the denominator. The quotient is the whole number, the remainder is the new numerator, and the denominator stays the same.
Worked example: Convert 11/4
- Divide 11 by 4. The quotient is 2 and the remainder is 3.
- Write the quotient as the whole number: 2.
- Write the remainder over the original denominator: 3/4.
- Combine them: 11/4 = 2 3/4.
Another example: Convert 17/5
17 ÷ 5 = 3 remainder 2. Therefore, 17/5 = 3 2/5.
5. Convert a Mixed Number to an Improper Fraction
Multiply the whole number by the denominator, add the numerator, and place the result over the original denominator.
Worked example: Convert 2 3/5
- Multiply the whole number by the denominator: 2 × 5 = 10.
- Add the numerator: 10 + 3 = 13.
- Keep the denominator: 5.
- Write the improper fraction: 2 3/5 = 13/5.
Another example: Convert 4 1/3
4 × 3 = 12; 12 + 1 = 13. Therefore, 4 1/3 = 13/3.
6. Convert in Both Directions: Quick Reference
| Starting form | Method | Result |
|---|---|---|
| 13/4 | 13 ÷ 4 = 3 remainder 1 | 3 1/4 |
| 2 2/3 | 2 × 3 + 2 = 8 | 8/3 |
| 19/5 | 19 ÷ 5 = 3 remainder 4 | 3 4/5 |
| 1 5/6 | 1 × 6 + 5 = 11 | 11/6 |
7. Compare the Values
When comparing a mixed number and an improper fraction, convert one form so both numbers can be compared more easily.
- Convert 1 2/3 to an improper fraction: (1 × 3 + 2)/3 = 5/3.
- Use a common denominator of 12: 5/3 = 20/12 and 7/4 = 21/12.
- Since 20/12 is less than 21/12, 1 2/3 is less than 7/4.
8. Common Mistakes to Avoid
9. Practice Exercises
Try these before revealing the answers.
- Is 4/7 a proper or improper fraction?
- Is 9/5 a proper or improper fraction?
- Convert 13/4 to a mixed number.
- Convert 22/6 to a mixed number and simplify the fractional part.
- Convert 3 2/7 to an improper fraction.
- Convert 5 3/4 to an improper fraction.
- Which is greater: 2 1/2 or 11/4?
Show practice answers and working
- Proper fraction; 4 is smaller than 7.
- Improper fraction; 9 is greater than 5.
- 13 ÷ 4 = 3 remainder 1, so 3 1/4.
- 22 ÷ 6 = 3 remainder 4, so 3 4/6 = 3 2/3.
- 3 × 7 + 2 = 23, so 23/7.
- 5 × 4 + 3 = 23, so 23/4.
- 2 1/2 = 10/4, and 11/4 is greater.
