• I can divide rational numbers.

Any division problem is actually a multiplication problem:

1. Find the missing values in the equations
   • -3 • 4 = ?

4. Han and Clare walk towards each other at a constant rate, meet up, and then continue past each other in opposite directions. We will call the position where they meet up 0 feet and the time when they meet up 0 seconds.

Han's velocity is 4 feet per second.

Clare's velocity is -5 feet per second.

• Where is each person 10 seconds before they meet up?
• When is each person at the position -10 feet from the meeting place?
