When it comes to mathematics, percentages are a crucial concept that is used in various fields, from finance to daily decision-making. One common question that arises is, “What number is 2% of 35?” While this might seem like a straightforward calculation, understanding percentages can provide valuable insights into your financial literacy and analytical skills. In this article, we will explore the concept of percentages, how to calculate them, and why knowing the answer to this question can empower you in your daily life.
The Basics of Percentages
A percentage represents a fraction out of 100. Thus, when we talk about “2%,” we are essentially saying “2 out of 100.” To grasp the calculation of a percentage, it’s essential to understand the following concepts:
Understanding the Components
Every percentage calculation involves two primary components:
- The Percentage: This is the portion or the part of the whole you are determining. In our example, it is 2%.
- The Whole (or Total): This is the number you want to find a percentage of—in this case, 35.
Having these two components laid out helps clarify the calculation process.
The Formula for Calculating a Percentage
To find out what number is a specific percentage of another number, you can use this simple formula:
Percentage Value = (Percentage/100) × Total
Where:
– Percentage is the value you want to find out of 100 (in this case, 2).
– Total is the number from which you want to calculate the percentage (here, 35).
Calculating 2% of 35
Now that we have a solid understanding of percentages, we can apply the formula to find 2% of 35.
Step-by-Step Calculation
- Identify the percentage and the whole:
- Percentage: 2%
-
Whole: 35
-
Plug these values into the formula:
- Convert the percentage to decimal form: 2% = 2/100 = 0.02.
- Now use the formula:
Percentage Value = 0.02 × 35
- Perform the multiplication:
- 0.02 × 35 = 0.7.
Therefore, 2% of 35 equals 0.7.
