Finding the solution to "What is 20/330?" involves simplifying fractions and converting them into percentages. This seemingly simple question opens the door to understanding fundamental mathematical concepts. Let's break down the process step-by-step.

Simplifying the Fraction 20/330

The fraction 20/330 represents 20 parts out of a total of 330 parts. To simplify this fraction, we need to find the greatest common divisor (GCD) of both 20 and 330. The GCD is the largest number that divides both numbers without leaving a remainder.

In this case, the GCD of 20 and 330 is 10. We divide both the numerator (20) and the denominator (330) by 10:

20 ÷ 10 = 2 330 ÷ 10 = 33

Therefore, the simplified fraction is 2/33. This means 20/330 is equivalent to 2/33; they represent the same proportion.

Converting the Fraction to a Percentage

To express 2/33 as a percentage, we need to convert the fraction into a decimal and then multiply by 100.

1. Convert to Decimal: Divide the numerator (2) by the denominator (33): 2 ÷ 33 ≈ 0.0606

2. Multiply by 100: Multiply the decimal by 100 to express it as a percentage: 0.0606 × 100 ≈ 6.06%

Therefore, 20/330 is approximately 6.06%.

Real-World Applications

Understanding how to simplify fractions and calculate percentages is crucial in many real-world situations:

• Calculating Discounts: If a store offers a 20/330 discount (which simplifies to a 6.06% discount), you can easily determine the price reduction.

• Analyzing Data: In statistics and data analysis, simplifying fractions and calculating percentages helps in understanding proportions and trends within datasets.

• Financial Calculations: Percentages are fundamental in financial calculations, including interest rates, profit margins, and tax calculations.

Further Exploration: Different Methods

While we used the GCD method to simplify the fraction, other approaches exist. You could also simplify the fraction step by step, dividing both numerator and denominator by common factors until you reach the simplest form. For example:

• Divide by 2: 20/330 = 10/165
• Divide by 5: 10/165 = 2/33

This iterative process achieves the same result as using the GCD directly. Choosing the most efficient method depends on individual preference and the complexity of the fraction.

Conclusion: 20/330 in its Simplest Form

In conclusion, 20/330 simplifies to the fraction 2/33, which is approximately equal to 6.06%. Mastering fraction simplification and percentage calculation is a valuable skill with numerous applications in everyday life and various fields of study. Understanding these fundamental mathematical concepts builds a stronger foundation for more advanced mathematical concepts.
