Dividing decimals can be a challenging task for most people. Decimal division requires precision and accuracy, but it’s not as complicated as it seems. With the right tools and knowledge, anyone can be a pro at dividing decimals in no time. In the next few paragraphs, we will discuss what decimals are and why they are important in everyday life.
What are Decimals?
Decimals are numbers that represent parts of a whole. They are used to express values that are not whole numbers, such as money, measurements, and percentages. A decimal point separates the whole number part from the decimal part.
For example:
| Whole Number | Decimal Number |
| 5 | 0.5 |
| 10 | 1.25 |
| 625 | 62.5 |
Understanding decimals is essential for various fields such as finance, engineering, and science. Decimal division is a fundamental math operation that comes in handy when solving real-world problems. In the following paragraphs, we will explain how to divide decimals step-by-step.
How to Divide Decimals
Step 1: Set Up
Write the dividend (the number to be divided) and the divisor (the number you are dividing by) in long division format. Place the decimal point in the dividend directly above the division sign.
For example:
| 5.5 | 32.25 |
Step 2: Move the Decimal
Move the decimal point in the divisor (the number you are dividing by) to the right until it becomes a whole number. Move the same number of places in the dividend (the number being divided).
For example:
| 5.5 | 32.25 | |
| ∙ | ↓ |
| 100 | 585 |
Step 3: Divide
Divide the whole number in the dividend by the whole number in the divisor. Write the quotient above the line.
For example:
| 5.5 | 32.25 | |
| ∙ | ↓ |
| 100 | 585 |
| 5 |
Step 4: Multiply and Subtract
Multiply the quotient by the divisor and write the product below the dividend. Subtract the product from the dividend and write the remainder below the line.
For example:
| 5.5 | 32.25 | |
| ∙ | ↓ |
| 100 | 585 |
| 5 | |
| 27.5 | |
| 27.5 | 3.75 |
Step 5: Bring Down the Next Digit
Bring down the next digit in the dividend and place it next to the remainder. This will create a new number to divide. Repeat steps 3 to 5 until there are no more digits to bring down.
For example:
| 5.5 | 32.25 | |
| ∙ | ↓ |
| 100 | 585 |
| 5 | |
| 27.5 | |
| 27.5 | 3.75 |
| 0 | 3.25 |
| 0 |
Step 6: Round the Answer
If necessary, round the quotient to the nearest hundredth or thousandth.
For example:
32.25 ÷ 5.5 = 5.86 (rounded to the nearest hundredth)
Step 7: Don’t Forget the Units
Include the correct units for your answer, such as dollars or meters.
For example:
If you are dividing 32.25 dollars by 5.5 people, the answer is 5.86 dollars per person.
FAQs
