At the end of this lesson, students should be able to divide decimals by 10, 100 or 1000.
Remember from the previous lesson that, when you multiply a decimal number by:
- 10, each digit of the decimal moves one place to the left.
- 100, each digit moves 2 places to the left.
- 1000, each digit moves 3 places to the left.
Moreover, division is the inverse of multiplication. Therefore:
- When multiplying a decimal by 10, move each digit of the decimalone place to the right.
- When multiplying by 100, move each digit 2 places to the right.
- When multiplying by 100, move each digit 3 places to the right.
