Here are the solutions to the problems on the worksheet.
Part A: Find the quotient
To solve these, remember the rule for dividing by 10, 100, and 1,000: move the decimal point to the
left.
* Divide by
10: Move the decimal
1 spot to the left.
* Divide by
100: Move the decimal
2 spots to the left.
* Divide by
1,000: Move the decimal
3 spots to the left.

0.0208
Row 2: Start with 12.71
* $\div 10$ (move 1 left):
1.271
* $\div 100$ (move 2 left):
0.1271
* $\div 1,000$ (move 3 left):
0.01271
Row 3: Start with 9.5
* $\div 10$ (move 1 left):
0.95
* $\div 100$ (move 2 left):
0.095
* $\div 1,000$ (move 3 left):
0.0095
Row 4: Start with 0.72
* $\div 10$ (move 1 left):
0.072
* $\div 100$ (move 2 left):
0.0072
* $\div 1,000$ (move 3 left):
0.00072
Row 5: Start with 87.6
* $\div 10$ (move 1 left):
8.76
* $\div 100$ (move 2 left):
0.876
* $\div 1,000$ (move 3 left):
0.0876
