Step-by-Step Simplification of 15/850

The first step in understanding 15/850 is simplifying it to its lowest terms. This means finding the greatest common divisor (GCD) of both the numerator (15) and the denominator (850) and dividing both by that GCD.

1. Finding the GCD: Let's find the prime factorization of both 15 and 850.

   • 15 = 3 x 5
   • 850 = 2 x 5 x 5 x 17 = 2 x 5² x 17

2. Identifying Common Factors: The only common factor between 15 and 850 is 5.

3. Simplifying the Fraction: Divide both the numerator and the denominator by the GCD (5):

   15 ÷ 5 = 3 850 ÷ 5 = 170

That's why, the simplified fraction is 3/170. This simplified form is much easier to work with and understand than the original fraction.

Converting to Decimal and Percentage

Simplifying the fraction makes converting it to a decimal and a percentage straightforward.

1. Converting to Decimal: Divide the numerator (3) by the denominator (170):

   3 ÷ 170 ≈ 0.0176

2. Converting to Percentage: Multiply the decimal by 100:

   0.0176 x 100 ≈ 1.76%

So, 15/850 is approximately equal to 0.Practically speaking, 0176 or 1. Now, 76%. This percentage representation allows for easier comparison and interpretation in various contexts.

Real-World Applications of 15/850 (or 3/170)

While 15/850 might not seem immediately relevant to everyday life, it can represent various scenarios:

• Surveys and Statistics: Imagine a survey of 850 people where 15 responded positively to a specific question. The fraction 15/850 (or 3/170) represents the proportion of positive responses. This could be crucial for understanding public opinion or market research.

• Manufacturing and Quality Control: If a factory produces 850 units and 15 are found to be defective, the fraction represents the defect rate. This information is vital for improving production processes and maintaining quality standards.

• Financial Calculations: In finance, this fraction could represent a portion of a portfolio, a percentage change in stock prices, or a part of a larger investment.
