1 Dividing by a Fraction

2 What does it mean to divide by a fraction?

3 Division of Fractions 5 ÷ ⅓ = ?

4 Division of Fractions 5 ÷ ⅓ =

5 Division of Fractions 5 ÷ ⅓ = 123 13 111210 1415 456789

6 Division of Fractions ⅓ ÷ 5 =

7 Why Don’t We Just Flip and Multiply?

8 Why Does “Flip and Multiply” Work? 5 ÷ ⅓ = 5 ∙ 3=15

9 Maintain the Value of the Quotient Invert and multiply vs. developing the concept of the procedure Learning the algorithm does not mean that you understand the mathematics, but understanding the mathematics can help you learn and remember the algorithm. Review the mathematics, it will help you understand the algorithm.
