4. Converting Improper Fractions to Mixed Numbers. There are times when we have to change improper fractions to mixed numbers. What is an improper fraction? What is a mixed number? Recall that a fraction is made up of a numerator and a denominator, separated by a dividing line as shown in Fig.1 below. Both a and b are integers, and b cannot be a 0.

5. A proper fraction will have a numerator that is smaller than the denominator. Examples of proper fractions: Proper Fraction NUMERATOR DENOMINATOR

6. An improper fraction on the other hand, is a fraction that has a numerator that is larger than the denominator. In all the examples below you can see that the value of the numerator a is greater than the value of the denominator b. Examples of improper fractions include: Improper Fraction

7. A mixed number has two parts – a whole number part and a fractional part. Examples of mixed numbers include: Mixed Number In other words, a mix number is the sum of its whole number and its fraction. comes from adding

8. How do we change improper fractions to mixed numbers ? To change an improper fraction to a mixed number, we divide the numerator by the denominator. We can then use the result to write the mixed number.

9. Example 1: Change to a mixed number. Solution: First we divide 7 by 4. As you can see, 4 goes into 7 only once. We have a remainder of 3. So we have the following: Our fraction is therefore equivalent to the mixed number

10. Example 2: Change to a mixed number. In this example, 7 goes into 29 four times, and we have a remainder of 1. We have: Therefore the improper fraction is equivalent to the mixed number Solution: First we divide 29 by 7.
