2. Dividing Fractions What does 4 ÷ 2 mean in words? Justify your reasoning by using a model or a drawing. how many groups of 2 are in 4? ÷ There are 2 groups of 2 in 4, therefore 4 ÷ 2 = 2

3. Example 1 What does 3/4 ÷ 2/3 mean in words? (How many groups of 2/3 are in 3/4)?

4. Example 1 3/4 ÷ 2/3 When dividing fractions, the denominators are still the dimensions of the arrays! Model a 4 by 3 array for each fraction. ÷

5. Example 1 3/4 ÷ 2/3 ÷ 2/33/4 Is equivalent to 9/12 Is equivalent to 8/12 Find out how many groups of 2/3 (8 units) are in 3/4 (9 units) There is 1 whole group of 8 and one more left out of another group of 8 1 1/8

6. 3/4 ÷ 2/3 ÷ 2/33/4 Is equivalent to 9/12 Is equivalent to 8/12

7. Example 2 1/2 ÷ 1/3 ÷ 1/31/2 Is equivalent to 3/6 Is equivalent to 2/6 Find out how many groups of 1/3 (2 units) are in 1/2 (3 units) There is 1 whole group of 2 and one more left out of another group of 2 1 1/2

8. 1/2 ÷ 1/3 ÷ 1/31/2 Is equivalent to 3/6 Is equivalent to 2/6

9. Example 3 2/3 ÷ 3/4 ÷ 3/42/3 Is equivalent to 8/12 Is equivalent to 9/12 Find out how many groups of 3/4 (9 units) are in 2/3 (8 units) YOU CAN’T GET A WHOLE GROUP OF 9 UNITS! There are only 8 out of a group of 9, so the quotient is 8/9

10. 2/3 ÷ 3/4 ÷ 3/42/3 Is equivalent to 8/12 Is equivalent to 9/12
