Multliply 5.55 by 103. Explain the shift of the digits and the change in the value of each digit.
When multiplying by 103, each digit shifts 3 places to the left. 103 equals 10 x 10 x 10, or 1,000, so each digit becomes 1,000 times larger.
5.55 x 103 = 5,550
Divide 46,507 by 103. Explain the shift of the digits and the change in the value of each digit.
When dividing by 103, each digit shifts 3 places to the right. 103 equals 10 x 10 x 10 or 1000, so each digit becomes one thousandth less.
46,507 / 1000 = 46.507
Round .499 to the nearest 1

Multiply 9.99 x 104.
Explain the shift of the digits and how that changes the value of each digit.
When multiplying by 104, each number shifts 4 places to the left. 104 equals 10 x 10 x 10 x 10 or 10,000, so each number becomes 10,000 times larger. 9.99 x 10,000 = 99,900
Divide 77,700 by 102. Explain the shift of the digits and the change in the value of each digit.
When dividing by 102, each digit shifts to the right 2 places. 102 equals 10 x 10, or 100. Therefore, each digit becomes one hundredth as large.
77,700 / by 100 = 777
