1. Lesson 9.9: Division of Decimals

3. Mental Math estimate the quotient and write the number model you used to solve it Example: 61/3 You write: 60/3 = 20 37/2 59/4 135/7 344/5621/81,946/204

4. Math Message In your Math Notebook, write a number story that could be solved by dividing 4.2 by 7. Be prepared to share your problem Breaking into equal parts: A ribbon is 4.2 meters long. It must be cut into 7 pieces of the same length. Money and sharing: Think of 4.2 as $4.20, which is to be shared equally among 7 students.

5. Estimating Quotients of Decimals We will learn to find the quotient of decimals Each problem shows the solution, but the decimal point is missing in the quotient. You can decide by estimating.
