Percentages are an integral part of our daily lives, used in various contexts from calculating discounts and interest rates to understanding statistical data and tracking progress. Understanding how to calculate percentages is a fundamental skill that empowers us to make informed decisions and navigate the world around us effectively. One common percentage calculation involves determining what percentage one number represents of another. For instance, “24 is what percent of 25?” This seemingly simple question can unlock valuable insights into proportions and ratios, highlighting the practical applications of percentages in everyday life.
The Foundation of Percentages
Before delving into the specific calculation of “24 is what percent of 25?”, it’s essential to grasp the fundamental concept of percentages. A percentage is a fraction expressed out of one hundred. The symbol “%” represents “out of one hundred,” so 50% signifies 50 out of every 100. Percentages provide a convenient way to express parts of a whole as a relative proportion.
Converting Fractions to Percentages
Fractions and percentages are closely related. To convert a fraction to a percentage, follow these steps:
- Divide the numerator (top number) of the fraction by the denominator (bottom number).
- Multiply the result by 100.
- Append the “%” symbol to the result.
For example, to convert the fraction 3/4 to a percentage:
0.75 x 100 = 75%
Calculating Percentages from Whole Numbers
When dealing with percentages of whole numbers, we essentially determine what fraction the given number represents of the total. Let’s illustrate this with an example: “What is 20% of 50?”
To calculate this, we can follow these steps:
- Convert the percentage to a decimal by dividing it by 100. In this case, 20% / 100 = 0.20
- Multiply the decimal by the whole number. 0.20 x 50 = 10
Therefore, 20% of 50 is 10. (See Also: How Much Math in Computer Science? You Need To Know)
Solving “24 is What Percent of 25?”
Now, let’s address the specific question: “24 is what percent of 25?”. To solve this, we can follow the same principles outlined above.
Step 1: Convert the Relationship to a Fraction
The question implies a relationship where 24 is a part of 25. We can express this as a fraction: 24/25.
Step 2: Convert the Fraction to a Decimal
Divide the numerator (24) by the denominator (25): 24 / 25 = 0.96
Step 3: Multiply by 100 to Express as a Percentage
Multiply the decimal (0.96) by 100: 0.96 x 100 = 96%
Therefore, 24 is 96% of 25.
Applications of Percentage Calculations
Understanding how to calculate percentages like “24 is what percent of 25?” has numerous practical applications in various fields:
Finance
