To find out what percent 7 is of 8, we can use a simple mathematical formula. Understanding this concept is essential for various applications, whether in academics, finance, or everyday life. Let’s delve deeper into the steps to determine the percentage and explore why understanding percentages is important.
Understanding Percentages
Percentages are a way of expressing a number as a fraction of 100. The term "percent" literally means "per hundred." This means that when we say "50 percent," we are referring to 50 out of every 100 parts. Percentages are used in various fields including mathematics, statistics, finance, and even in daily decision-making.
The Formula for Finding Percentage
To calculate what percent one number is of another, you can use the following formula:
[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]
In this case:
- Part = 7
- Whole = 8
Calculating 7 out of 8
Using the formula provided, we can substitute the values to find the percentage.
[ \text{Percentage} = \left( \frac{7}{8} \right) \times 100 ]
Now, let's perform the calculation:
-
Divide 7 by 8:
[ \frac{7}{8} = 0.875 ]
-
Multiply the result by 100 to convert it into a percentage:
[ 0.875 \times 100 = 87.5% ]
Conclusion on the Calculation
Therefore, 7 is 87.5% of 8. This percentage can be essential in contexts where you need to compare proportions or understand ratios in a more digestible format.
