Understanding Percentages

Percentages are a way to express a number as a fraction of 100. They are commonly used in various fields including finance, statistics, and general math. The concept of percentages helps in making comparisons, assessing discounts, and understanding proportions.

Key Formula for Calculating Percentages

The basic formula for converting a fraction to a percentage is:

[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]

In this case, the "Part" is 7 and the "Whole" is 8.

Step-by-Step Calculation

1. Identify the Part and the Whole: For our calculation, the part is 7, and the whole is 8.

2. Divide the Part by the Whole: [ \frac{7}{8} = 0.875 ]

3. Multiply by 100 to get the Percentage: [ 0.875 \times 100 = 87.5% ]

Thus, 7 out of 8 is equivalent to 87.5%. 🎉
