3. 1 2 2 5 3 9 4 8 2 6 2 8 5 15 1 4 4 6 2 4 3 7 5 9 4 12 9 18 4 10 25 75 30 75 49 98 8 16 3 12 14 35 19 76 25 70 33 99

4. Match up the fraction on the left with its equivalent on the right. 2 5 1 3 3 7 4 9 3 8 19 57 24 60 12 28 24 64 84 189

5. An improper fraction is one where the numerator (top number) is bigger than the denominator (bottom number). This means that there must be more than one whole one. e.g. = 1 3 2 = 15 4 =

6. e.g. 3 2 = 15 4 = 1 2 = 3 3 4 An improper fraction can also be written as a mixed number. This means a whole number and a fraction.

7. Mixed Number Improper Fraction Mixed Number Improper Fraction

9. To convert an improper fraction into a mixed number: How many times does the denominator go into the numerator ? This is the whole number part. The remainder is the numerator of the fraction part.

10. Example: How many times does 9 go into 38? What is the remainder? 38 9 = 4 2 9

11. To convert a mixed number into an improper fraction : Multiply the whole number by the denominator then add the numerator This is the numerator of the improper fraction The denominator stays the same.

12. Example: 3 5 7 How many sevenths is 3 whole ones? 3 x 7 = 21 = 21 7 + 5 7 = 26 7
