Lesson 13- Dividing Decimals By 10, 100 Or 1000 Objective

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.
