Dividing Decimals by Powers of Ten (Part 2)

The video tutorial explains how to divide decimal numbers by powers of 10. It introduces the concept by showing that dividing a decimal by a power of 10 involves moving the decimal point to the left by as many places as the power of 10. The tutorial provides examples to illustrate this rule, demonstrating how to divide decimals by 10 squared and 10 cubed. The lesson concludes by summarizing the key points learned.

What happens to the digits of a decimal number when it is divided by 10 to the power of 2?

• The decimal point moves one place to the left.

• Each digit moves two places to the right.

• Each digit moves two places to the left.

• The decimal point moves two places to the right.

According to the general rule, how do you divide a decimal by a power of 10?

• Move the decimal point to the right as many places as the power of 10.

• Move the decimal point to the left as many places as the power of 10.

• Multiply the number by 10.
