1. Simplifying 15/900 to its Lowest Terms

Simplifying a fraction means reducing it to its smallest equivalent form. This is achieved by finding the greatest common divisor (GCD) of the numerator (15) and the denominator (900) and dividing both by it.

Let's find the GCD of 15 and 900. We can use the prime factorization method:

• 15: 3 x 5
• 900: 2 x 2 x 3 x 3 x 5 x 5 = 2² x 3² x 5²

The common factors between 15 and 900 are 3 and 5. So, the GCD is 3 x 5 = 15.

Now, divide both the numerator and the denominator by the GCD:

15 ÷ 15 = 1 900 ÷ 15 = 60

Which means, the simplified form of 15/900 is 1/60.

2. Converting 1/60 to a Decimal

To convert a fraction to a decimal, divide the numerator by the denominator:

1 ÷ 60 = 0.0166666...

This decimal is a repeating decimal, with the digit 6 repeating infinitely. For practical purposes, we can round this to a certain number of decimal places, such as 0.017 (rounded to three decimal places) or 0.0167 (rounded to four decimal places).

3. Converting 1/60 to a Percentage

To convert a fraction to a percentage, multiply the decimal equivalent by 100:

0.016666... x 100 ≈ 1.67%

4. Visualizing 15/900 and 1/60

Imagine a pie chart. If the entire pie represents 900 units, then 15/900 represents 15 of those units. This is a small slice of the pie. In real terms, simplifying the fraction to 1/60 means that it represents one part out of sixty equal parts of the whole pie. This visual representation helps to understand the relative magnitude of the fraction.

5. Real-World Applications of 15/900 (and 1/60)

While 15/900 might not immediately appear in everyday scenarios, understanding its simplification and equivalent representations allows for easier application in various contexts:

• Proportions and Ratios: Imagine a class of 900 students, where 15 students achieved a perfect score on a test. The fraction 15/900, simplified to 1/60, represents the proportion of students who achieved a perfect score. This can be used to compare this performance with other classes or tests.

• Percentage Calculations: In sales, a discount of 1.67% (equivalent to 1/60) could be applied to the price of an item. Understanding the fractional representation helps in calculating the actual discount amount.

• Probability: If there's a one in sixty chance of a specific event occurring (1/60), understanding the fractional representation is critical for assessing risk and making informed decisions.

6. Further Exploration of Fraction Simplification

The simplification of 15/900 highlights the importance of finding the greatest common divisor (GCD). There are several methods to determine the GCD, including:

• Prime Factorization: This method involves breaking down the numbers into their prime factors and identifying the common factors. This is the method used above.
