How many one-hundred dollar bills do you need to make \$2,000? \$20,000?
How many ten dollar bills do you need to make \$2,000? \$20,000?
How many dimes do you need to make \$0.20? \$2? \$20?
How many pennies do you need to make \$0.02? \$0.20? \$2?
Use the answers to the questions above to fill in the table:
|  $A$   | $B$  | $A\div B$ |
|--------|------|-----------|
|   2    | 0.01 |           |
|   20   | 0.1  |           |
|  200   |  1   |           |
| 2,000  |  10  |           |
| 20,000 | 100  |           |
What changes (and how does it change) and what stays the same as you move from row to row down the table?
