   11.97
-7.23
------


2. Subtract the hundredths: 7 – 3 = 4.

3. Subtract the tenths: 9 – 2 = 7.

4. Subtract the whole numbers: 11 – 7 = 4.

The final answer is 4.74.

This process works for all decimal subtraction problems, not just for these two numbers.

Why Does This Calculation Matter?

Now that we know the result, let’s see why what is the difference between 11.97 and 7.23 matters in real life.

1. Everyday Shopping

Imagine you’re comparing two prices: one item costs $11.97 and another costs $7.23. The price difference of $4.74 shows how much more expensive the first product is.

2. Budgeting

If you had $11.97 in your wallet and you spent $7.23, the money left would be exactly $4.74. This simple subtraction is key to tracking spending and saving.

3. Business Profits

Common Mistakes in Decimal Subtraction

Even though solving what is the difference between 11.97 and 7.23 seems straightforward, people often make errors such as:

• Not lining up decimals correctly, which leads to inaccurate answers.

• Forgetting placeholder zeros when one number has fewer decimal places.

• Borrowing mistakes during subtraction when the top digit is smaller than the bottom digit.

By practicing carefully, these mistakes can easily be avoided.

Checking the Answer

A great way to confirm subtraction is to add the difference back to the smaller number. For example:

$$7.23+4.74=11.97$$

Since this equals the original larger number, the subtraction is correct.

Real-Life Scenarios Using 11.97 and 7.23

To make the calculation more relatable, here are some practical uses of this specific difference:

• Meal Cost: If lunch costs $11.97 and breakfast was $7.23, then you spent $4.74 more on lunch.

• Fuel Prices: If gasoline costs $11.97 in one city and $7.23 in another, the price difference is $4.74 per unit.

• School Supplies: Buying two items with these prices would show a cost difference of $4.74.

These examples highlight why even small differences in numbers matter.

Connecting to Percentages

Sometimes, it’s not enough to just know the difference. People also want to know what percentage one number is smaller or larger. For instance:

Percentage Difference=11.97−7.2311.97×100\text{Percentage Difference} = \frac{11.97 – 7.23}{11.97} \times 100Percentage Difference=11.9711.97−7.23​×100 =4.7411.97×100≈39.61%= \frac{4.74}{11.97} \times 100 \approx 39.61\%=11.974.74​×100≈39.61%

So, the lower value (7.23) is about 40% less than 11.97.

Tips for Mastering Decimal Subtraction

To solve problems like what is the difference between 11.97 and 7.23 quickly and accurately, keep these tips in mind:

1. Always line up decimal points.

2. Double-check the subtraction step by step.

3. Use real-life examples to practice.

4. Verify the answer by adding the result to the smaller number.

These techniques improve both speed and accuracy.

Why This Question is Useful for Students

Teachers often use simple decimal problems like this one in classrooms because they:

• Help students practice alignment of decimals.

• Encourage accuracy in handling money-related math.

• Build a foundation for advanced concepts like percentages and ratios.

Learning these basics early makes more complex math much easier later.

Conclusion

To summarize, what is the difference between 11.97 and 7.23? The correct answer is 4.74. While the calculation itself is simple, the skill behind it is valuable in shopping, budgeting, finance, and education.
