Step-by-Step Guide: What Is the Difference Between 11.97 and 7.23
To find the difference between 11.97 and 7.23, you subtract the smaller number from the larger one. Since 11.97 is larger than 7.23, the calculation is 11.97 – 7.23. Let’s break it down into clear steps for a 6th- to 8th-grade reading level.
Step 1: Align the Numbers by Decimal Points
When subtracting decimals, line up the decimal points to keep the place values organized. Here’s how it looks:
11.97
- 7.23
-------
Both numbers have two decimal places, so no additional zeros are needed.
Step 2: Subtract Each Column
Start from the rightmost digit and move left, handling each place value carefully.
- Hundredths Place: 7 – 3 = 4
- Tenths Place: 9 – 2 = 7
- Units Place: 1 – 7 requires borrowing. Take 1 from the tens place, making the units place 11. Then, 11 – 7 = 4.
- Tens Place: After borrowing, the tens place becomes 0 (from 1 – 1). So, 0 – 0 = 0.
- Decimal Point: Carry over the decimal point to the answer.
The result is 4.74.
Step 3: Verify the Calculation
To ensure accuracy, add the difference back to the smaller number:
7.23 + 4.74 = 11.97
This confirms the calculation is correct.
So, the difference between 11.97 and 7.23 is 4.74.
Visualizing the Calculation with a Table
Here’s a table to summarize the subtraction process:
Place Value | 11.97 | 7.23 | Difference |
---|---|---|---|
Tens | 1 | 0 | 0 |
Units | 1 | 7 | 4 (after borrowing) |
Decimal Point | . | . | . |
Tenths | 9 | 2 | 7 |
Hundredths | 7 | 3 | 4 |
Result: 4.74
This table makes it easy to see how each digit is subtracted, ensuring clarity for beginners.

Common Mistakes to Avoid When Subtracting Decimals
Subtracting decimals can be tricky if you’re not careful. Here are common errors and how to avoid them:
- Misaligning Decimal Points: Always line up the decimals to avoid place value mistakes.
- Forgetting to Borrow: If a digit in the top number is smaller than the bottom one, borrow from the next place value.
- Ignoring Decimal Places: Ensure the answer has the same number of decimal places as the numbers being subtracted.
Double-checking your work, as shown in the verification step, helps catch these errors.
