What is 25 of 42? Understanding Fractions and Percentages

The question "What is 25 of 42?" can be interpreted in a couple of ways, both involving the concept of fractions and percentages. Let's explore both interpretations:

1. 25 as a Fraction of 42

This interpretation asks what fraction 25 represents when compared to the whole, 42. To find this, we simply express the relationship as a fraction:

25/42

This fraction is already in its simplest form, as 25 and 42 share no common factors other than 1. Therefore, 25 out of 42 is represented by the irreducible fraction 25/42.

2. 25 as a Percentage of 42

This interpretation asks what percentage 25 represents of the total 42. To calculate this, we can use the following formula:

(Part / Whole) * 100%

In this case:

(25 / 42) * 100%

Performing the calculation:

(25 / 42) ≈ 0.5952

0.5952 * 100% ≈ 59.52%

Therefore, 25 is approximately 59.52% of 42.

Different Ways to Express the Relationship

It's important to understand that 25/42, 0.5952, and 59.52% all represent the same relationship between 25 and 42. The best way to express this relationship depends on the context. For example:

• Fractions: Useful for precise representation and further mathematical calculations.
• Decimals: Useful for calculations involving other decimal numbers.
• Percentages: Useful for easy understanding and comparison in real-world scenarios.

Practical Applications

Understanding how to calculate fractions and percentages is crucial in many everyday situations, including:

• Calculating discounts: Finding the sale price of an item.
• Determining tax rates: Figuring out the total cost including taxes.
• Analyzing data: Interpreting statistical information.
• Financial planning: Tracking budgeting and investments.

By understanding the different ways to express the relationship between 25 and 42, you can apply these skills to a wide range of problems. Remember that whether you use fractions, decimals, or percentages, the underlying relationship remains the same.
