4. Move the decimal to the right: two spaces
Ex 1) x 100
Move the decimal to the right: two spaces
149.2

5. Ex 2)15.36 x 1,000
Move the decimal point to the right: three spaces
Add a zero for the third space.
15,360

6. The Basics of Dividing:
When you divide by 10, 100, or 1,000, you can move the decimal point to the left. Move the decimal point once for each zero you are dividing by.

7. Ex 3) 2, ÷ 1,000
Move the decimal to the left: three spaces

8. Move the decimal to the left: two spaces
