Multiplication of Decimals
To multiply two decimals, first multiply them as whole numbers, then count the total number of decimal places in both numbers and place the decimal point in the product accordingly.
Division by Powers of 10
When dividing a decimal number 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 a Whole Number
Divide normally as with whole numbers, placing the decimal point in the quotient directly above the decimal point in the dividend.
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 do I shift the decimal point when multiplying by 100?
When multiplying by 100, you shift the decimal point two places to the right because 100 has two zeros.
How do I divide a decimal by another decimal?
First, remove the decimal from the divisor by multiplying both the dividend and the divisor by the same power of 10, then perform normal long division.
What should I do if there are not enough digits when shifting a decimal point?
You can add zeros as placeholders to the left or right to make up for the required number of decimal places.
