Finding what percentage one number represents of another is a common calculation in many areas, from calculating grades to determining sales increases. Let's break down how to determine what percentage of 40 is 35. This seemingly simple question can be solved using a straightforward formula.

Understanding the Percentage Formula

The fundamental formula for calculating percentages is:

(Part / Whole) * 100% = Percentage

In our case:

• Part: 35 (the number we want to express as a percentage)
• Whole: 40 (the total number)

Calculating the Percentage

1. Divide the Part by the Whole:

   35 / 40 = 0.875

2. Multiply by 100%:

   0.875 * 100% = 87.5%

Therefore, 35 is 87.5% of 40.

Alternative Method: Using Proportions

Another way to solve this problem is by setting up a proportion:

35/40 = x/100

To solve for 'x' (the percentage):

1. Cross-multiply: 35 * 100 = 40 * x
2. Simplify: 3500 = 40x
3. Divide both sides by 40: x = 3500 / 40 = 87.5

Again, we arrive at the answer: 35 is 87.5% of 40.

Practical Applications

Understanding percentage calculations is crucial in various real-world scenarios:

• Grade Calculation: If you scored 35 out of 40 on a test, your score is 87.5%.
• Sales and Discounts: If an item originally priced at $40 is on sale for $35, the discount is 87.5% of the original price. (Note: this would actually be a 12.5% discount, as 100% - 87.5% = 12.5%).
• Financial Analysis: Percentage changes in investments, profits, and expenses are frequently calculated using this method.

Conclusion

Determining what percentage of 40 is 35 involves a simple calculation using the percentage formula or proportions. The answer is 87.5%, a valuable piece of information applicable across numerous contexts. Remember to always clearly identify the "part" and the "whole" before applying the formula to avoid errors.
