Multiplication of Decimals by Whole Numbers
Multiply the numbers as whole numbers ignoring the decimal point, then place the decimal point in the product to have as many decimal places as the multiplicand.
Multiplication of Decimals by 10, 100, and 1000
When a decimal is multiplied by 10, 100, or 1000, the decimal point shifts to the right by as many places as there are zeros in the multiplier.
Division of Decimals by Whole Numbers
Divide the decimal number by the whole number as usual, and place the decimal point in the quotient directly above the decimal point in the dividend.
Division of Decimals by 10, 100, and 1000
When a decimal is divided by 10, 100, or 1000, the decimal point shifts to the left by as many places as there are zeros in the divisor.
Division of a Decimal by another Decimal
Convert the divisor into a whole number by shifting the decimal point to the right, and shift the decimal point in the dividend by the exact same number of places before dividing.

Frequently Asked Questions
Which direction does the decimal point move when multiplying by 100?
The decimal point moves to the right by two places because 100 has two zeros.
How do we divide a decimal number by another decimal number?
First, shift the decimal point of the divisor to the right to make it a whole number, and shift the decimal point of the dividend by the same number of places, then divide normally.
Why do we add zeros when multiplying or dividing decimals?
We add placeholder zeros when there are not enough digits to shift the decimal point during multiplication or division by powers of 10.
