Understanding Fractions and Percentages

Before diving into the conversion, let's briefly recap the concepts of fractions and percentages. A fraction represents a part of a whole, expressed as a ratio of two numbers (numerator and denominator). A percentage, on the other hand, represents a fraction of 100, denoted by the symbol %. Converting a fraction to a percentage involves finding the equivalent fraction with a denominator of 100.

Converting 10/15 to a Percentage: Step-by-Step

Here's how to convert the fraction 10/15 to a percentage:

1. Simplify the Fraction: The first step is to simplify the fraction 10/15. Both the numerator (10) and the denominator (15) are divisible by 5. Simplifying, we get 2/3.

2. Convert to a Decimal: To convert the simplified fraction 2/3 to a decimal, divide the numerator (2) by the denominator (3). This gives us approximately 0.6667 (we'll round to four decimal places for accuracy).

3. Convert Decimal to Percentage: To convert a decimal to a percentage, multiply the decimal by 100 and add the % symbol. So, 0.6667 multiplied by 100 equals 66.67%.

Therefore, 10/15 is equal to 66.67%.

Alternative Method: Direct Percentage Calculation

You can also calculate the percentage directly from the original fraction:

1. Set up a proportion: You can express the problem as a proportion: 10/15 = x/100, where 'x' represents the percentage.

2. Cross-multiply: Cross-multiplying gives you 15x = 1000.

3. Solve for x: Dividing both sides by 15 gives you x ≈ 66.67.

Therefore, again, 10/15 is approximately 66.67%.

Practical Applications and Further Learning

This simple conversion is used extensively in many real-world situations. For example, calculating discounts, determining grades, or understanding statistical data often requires converting fractions to percentages. Mastering this skill will greatly enhance your mathematical abilities and problem-solving skills.
