Explain how the position of the decimal point changes in a quotient as you divide a number by 10, 100, and 1,000.

• The decimal point moves to the left one time for each zero.

• The decimal point moves to the right time for each zero.

Choose all the correct equations.

• 223 ÷ 1 = 223

• 223 ÷ 10 = 22.3

• 223 ÷ 100 = 22.3

• 223 ÷ 1,000 = 0.223

Choose all the correct equations.

• 61 ÷ 1 = 61

• 61 ÷ 10 = 61.1

• 61 ÷ 100 = 0.61

• 61 ÷ 1,000 = 0.061

Choose all the correct equations.

• 57.4 ÷ 1 = 57.4
