Multiplying and Dividing by 10

When we multiply or divide by 10, 100 or 1000 the place values of the digits change but the digits themselves do not.

67 × 10

67 × 10

  • When we multiply by 10, all the digits shift one place value to the left.
    • 67 × 10 = 670
5.2 × 1,000

5.2 × 1,000

  • When we multiply by 1000, all the digits shift three place values to the left.
    • 5.2 × 1,000 = 5,200
7640 ÷ 100

7640 ÷ 100

  • When we divide by 100, all the digits shift two place values to the right.
    • 7,640 ÷ 100 = 76.4
0.18 ÷ 10

0.18 ÷ 10

  • When we divide by 10, all the digits shift one place value to the right.
    • 0.18 ÷ 10 = 0.018
