Dividing Decimals Made Easy
When it comes to dividing decimals, many of us get nervous. The good news is that dividing decimals is actually quite straightforward, and with a few simple tricks, you can master it in no time. In this article, we’ll explore five easy ways to divide decimals, so you can tackle even the toughest math problems with confidence.
Method 1: The Move-the-Decimal Trick
This is perhaps the easiest way to divide decimals. The basic idea is to move the decimal point in the divisor (the number you’re dividing by) to the right, and then move the decimal point in the dividend (the number being divided) to the right by the same number of places.
Example: 4.8 ÷ 0.6
- Move the decimal point in 0.6 to the right: 6
- Move the decimal point in 4.8 to the right by the same number of places: 48
- Now, divide 48 by 6: 48 ÷ 6 = 8
- So, 4.8 ÷ 0.6 = 8
Method 2: Convert to Whole Numbers
Another way to divide decimals is to convert them to whole numbers. This involves multiplying both the dividend and the divisor by a power of 10.
Example: 2.5 ÷ 0.5
- Multiply both numbers by 10: 25 ÷ 5
- Now, divide 25 by 5: 25 ÷ 5 = 5
- So, 2.5 ÷ 0.5 = 5
Method 3: Use a Calculator
Let’s face it – sometimes, the easiest way to divide decimals is to use a calculator! With a calculator, you can simply punch in the numbers and get the answer instantly.
Example: 7.2 ÷ 0.9
- Enter the numbers into the calculator: 7.2 ÷ 0.9
- Press the equals button: 8
Method 4: Use a Decimal Division Chart
A decimal division chart is a handy tool that can help you divide decimals quickly and easily. You can create your own chart or use one that’s pre-made.
Example: 9.6 ÷ 0.8
| Divisor | Quotient |
|---|---|
| 0.8 | 12 |
- Find the divisor (0.8) on the chart
- Look up the corresponding quotient (12)
- So, 9.6 ÷ 0.8 = 12
Method 5: Break Down the Problem
Finally, you can break down the problem into smaller, more manageable parts. This involves dividing the decimal into whole numbers and decimals, and then solving each part separately.
Example: 12.4 ÷ 2.5
- Break down the problem: 12 ÷ 2 + 0.4 ÷ 2.5
- Solve each part separately:
- 12 ÷ 2 = 6
- 0.4 ÷ 2.5 = 0.16
- Add the answers together: 6 + 0.16 = 6.16
📝 Note: When breaking down the problem, make sure to line up the decimal points correctly.
In conclusion, dividing decimals doesn’t have to be difficult. With these five easy methods, you can tackle even the toughest decimal division problems with confidence. Whether you’re using the move-the-decimal trick, converting to whole numbers, using a calculator, a decimal division chart, or breaking down the problem, you’ll be a pro at dividing decimals in no time.
