Rule for Multiplication and Division of Decimal Fractions
When multiplying or dividing decimal fractions, the process involves a few key steps.
Multiplication of Decimal Fractions: To multiply decimal fractions, follow these steps: 1. Step 1: Ignore the decimal points and multiply the numbers as if they were whole numbers. 2. Step 2: Count the total number of decimal places in the numbers being multiplied. 3. Step 3: Place the decimal point in the product so that the number of decimal places in the product is equal to the total number of decimal places in the numbers being multiplied.
For example: - To multiply 7.12 by 2, you would: - Ignore the decimal points and multiply 712 by 2 to get 1424. - Since 7.12 has two decimal places and 2 has zero decimal places, the product should have a total of two decimal places. Therefore, the result is 14.24.
Division of Decimal Fractions: To divide decimal fractions, follow these steps: 1. Step 1: Move the decimal point in the divisor to make it a whole number. Then move the decimal point in the dividend the same number of places to the right. 2. Step 2: Perform the division as if the numbers were whole numbers. 3. Step 3: Place the decimal point in the quotient directly above the decimal point in the dividend.
For example: - To divide 43.12 by 10, you would: - Move the decimal point in 10 to the right to make it 100. Then move the decimal point in 43.12 one place to the right to make it 431.2. - Perform the division as if they were whole numbers, which gives a quotient of 43.12. These steps provide a clear guide for multiplying and dividing decimal fractions.
