The Basics of Multiplying: When you multiply by 10, 100, or 1,000, you can move the decimal point to the right. The number of decimal places you move is the same as the number of zeroes you are multiplying by. When you multiply by 10, 100, or 1,000, you can move the decimal point to the right. The number of decimal places you move is the same as the number of zeroes you are multiplying by.

Ex 1) 1.492 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) 2,124.94 ÷ 1,000 Move the decimal to the left: three spaces. 2.12494

8
Ex 4) 4.2 ÷ 100 Move the decimal point to the left: two spaces. Add a zero for the second space..042
