How to Divide Decimals by Whole Numbers
Dividing decimals by whole numbers is a straightforward process. Here’s a step-by-step guide to help you understand and perform this operation easily:
Step 1: Set up the division problem
Write the decimal number (the dividend) inside the division bracket and the whole number (the divisor) outside. Example: Divide 12.6 by 3.
Step 2: Ignore the decimal point initially
Treat the decimal number as if it were a whole number by temporarily ignoring the decimal point. For 12.6, think of it as 126.
Step 3: Divide as usual
Divide the number as you would with whole numbers. 126 ÷ 3 = 42
Step 4: Place the decimal point in the quotient
Count how many digits are after the decimal point in the original decimal number. In 12.6, there is 1 digit after the decimal. Place the decimal point in the quotient so that it has the same number of digits after the decimal point. So, 42 becomes 4.2.
Final answer:
12.6 ÷ 3 = 4.2
Additional Tips
- If the decimal has more digits, just remember to place the decimal point in the quotient accordingly.
- You can check your answer by multiplying the quotient by the divisor.
- If the division doesn’t come out evenly, you can continue dividing to get more decimal places in the answer.
