Understanding Percentages
Percentages represent a fraction of 100. When we say "percentage," we essentially mean "out of 100." For example, 50% of a number means half of that number. To calculate the percentage of a number, you can use the formula:
[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]

Step-by-Step Calculation
Let's break down the calculation into clear steps:
-
Identify the part and the whole:
- Part = 11
- Whole = 15
-
Plug into the formula: [ \text{Percentage} = \left( \frac{11}{15} \right) \times 100 ]
-
Perform the division: [ \frac{11}{15} \approx 0.7333 ]
-
Multiply by 100 to find the percentage: [ 0.7333 \times 100 \approx 73.33 ]
So, 11 out of 15 is approximately 73.33%. 🎉
