To calculate 24 as a percentage of 30, we need to understand the basic formula for finding percentages. The formula is as follows:
[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]
In this case, 24 is the part, and 30 is the whole. Plugging these numbers into the formula, we have:
[ \text{Percentage} = \left( \frac{24}{30} \right) \times 100 ]
Now, let's break this down step by step to uncover the truth behind the calculation.

Real-Life Application of Percentages
Understanding how to work with percentages is vital in our daily lives. Here are some practical examples:
Example 1: Shopping Discounts
If a store is offering 30% off an item that originally costs $30, you can calculate how much you save:
[ \text{Discount} = 30 \times \frac{30}{100} = 9 ]
So, the final price would be:
[ 30 - 9 = 21 ]
Example 2: Analyzing Test Scores
If you scored 24 out of 30 on a quiz, knowing that this is 80% allows you to assess your performance quickly. It’s a great way to see if you are meeting your study goals or if there’s room for improvement.
Example 3: Fitness Goals
If you're trying to lose 30 pounds and have successfully lost 24 pounds, you can calculate the percentage of your goal you have achieved:
[ \text{Achievement} = \left( \frac{24}{30} \right) \times 100 = 80% ]
This is a strong motivator to keep pushing toward your goal!
Important Notes on Calculating Percentages
"Always remember to express the part in relation to the whole. If the whole changes, so will the percentage."
Understanding this key point ensures accurate calculations in any context where percentages are used.
Conclusion
In summary, calculating 24 as a percentage of 30 is a straightforward process that results in 80%. This knowledge not only helps in academic settings but extends into everyday decision-making. Whether you're shopping, setting personal goals, or analyzing data, knowing how to calculate percentages effectively is a skill worth mastering.
