The Correct Answer and Explanation is :
The correct answer is a. 24.
To calculate 60% of 40, you can use the formula for finding a percentage of a number, which is:
[
\text{Percentage} \times \text{Total} = \text{Value}
]
In this case, we are looking for 60% of 40. First, convert the percentage to a decimal by dividing it by 100:
[
60\% = \frac{60}{100} = 0.6
]
Next, multiply this decimal by the total number (40):
[
0.6 \times 40
]
Calculating this gives:
[
0.6 \times 40 = 24
]
Thus, 60% of 40 is 24.
Understanding percentages is crucial in various real-world contexts, from finance to healthcare. Percentages help us quantify parts of a whole and make comparisons easier. For example, in healthcare, understanding percentages can help professionals interpret lab results, dosages, and patient statistics. If a medication has a recommended dosage of 60% of a certain value, knowing how to calculate that quickly can be vital for patient care.
Additionally, percentages are prevalent in sales and marketing, where discounts are often expressed as percentages. For instance, if a product originally costs $40 and is marked down by 60%, knowing that the sale price would be 40% of the original price can help consumers assess the value of the deal.
In conclusion, the process of calculating 60% of 40 demonstrates the straightforward nature of percentage calculations. Mastering these basic math skills enhances critical thinking and decision-making abilities in everyday life, from budgeting to analyzing data trends.
