Table of Contents :
To find out what percentage 30 is of 50, we can follow a simple mathematical process. This process is not only straightforward but also quite useful in various real-life situations, including budgeting, comparing scores, or analyzing data. Let’s dive into the calculation and understand how to determine the percentage effectively. 📊
Understanding Percentages
Percentages are a way of expressing a number as a fraction of 100. The symbol for percentage is “%,” which means “per hundred.” Thus, when we want to find out what percentage a number (in this case, 30) is of another number (50), we can use the following formula:
Percentage Formula
The formula to calculate the percentage is:
[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]
Where:
- Part is the number we want to find the percentage of (30 in this case).
- Whole is the total number (50 in this case).
Step-by-Step Calculation
Let’s apply the formula step by step to find out what percentage 30 is of 50.
Step 1: Identify the Part and the Whole
- Part = 30
- Whole = 50
Step 2: Substitute the Values into the Formula
Now we substitute the values into the percentage formula:
[ \text{Percentage} = \left( \frac{30}{50} \right) \times 100 ]
Step 3: Perform the Division
Now, let’s calculate ( \frac{30}{50} ):
[ \frac{30}{50} = 0.6 ]
Step 4: Multiply by 100
Now, we multiply the result by 100 to convert it to a percentage:
[ 0.6 \times 100 = 60% ]
So, 30 is 60% of 50. 🎉
