Multiplication of Decimals by Whole Numbers
To multiply a decimal by a whole number, multiply them normally as whole numbers and then place the decimal point in the product to match the number of decimal places in the given decimal.
Multiplication of Decimals by Decimals
Multiply the two decimal numbers ignoring the decimal points, then count the total number of decimal places in both multipliers and place the decimal point in the product from right to left.
Division of Decimals by Powers of 10
When dividing a decimal number by 10, 100, or 1000, move the decimal point to the left by as many places as there are zeros in the divisor.
Division of a Decimal by a Whole Number
Divide the decimal number by the whole number as you would with whole numbers, placing the decimal point in the quotient directly above the decimal point in the dividend.
Conversion of Units using Decimals
Decimals are widely used to convert smaller units to larger units, such as expressing centimeters to meters or paisa to rupees using fractional parts.

Frequently Asked Questions
How do I know where to place the decimal point when multiplying two decimals?
Count the total number of decimal digits after the point in both numbers you are multiplying. Your final answer must have that same total count of digits to the right of the decimal point.
What should I do if the divisor has a decimal point during division?
Multiply both the dividend and the divisor by 10, 100, or 1000 to shift the decimal point in the divisor to the right until it becomes a whole number, then divide normally.
Which direction do I move the decimal point when dividing by 100?
You move the decimal point two places to the left because 100 has two zeros.
