In this lesson, we will look at dividing a decimal number by another decimal number.
When one decimal number is divided by another decimal number,
Step 1: Change the divisor to a whole number by moving the decimal point to the right until after the last digit.
Step 2: The decimal point of the dividend must also be moved by the same number of decimal places.
Step 3: Perform the division in the same way as dividing by a whole number. Place the decimal point of the quotient (answer) directly above the decimal point of the dividend.
The following diagram shows how to divide a decimal by a decimal. Scroll down the page for more examples and solutions.Example:
Evaluate 5.421 ÷ 0.03
Solution:
The divisor, 0.03, is moved 2 decimal places to form the whole number 3. The dividend, 5.421, is then also moved 2 decimal places to form 542.1. We then perform the division as shown:
