Mathematics often feels like a world of its own, filled with concepts and mysteries waiting to be unraveled. One such intriguing puzzle involves the decimal representation of the fraction 1/17, specifically the number 0.0588235294117647. This decimal has a repeating pattern that can lead us to discover the 300th digit in its sequence. Let’s embark on this mathematical adventure together!
Understanding the Decimal
The number 0.0588235294117647 is not just a random string of digits; it is the decimal expansion of the fraction 1/17. When we divide 1 by 17, we obtain a repeating decimal, which means that after a certain point, the digits start to repeat indefinitely.
The decimal representation of 1/17 is:
0.0588235294117647058823529411764705882352941176470588235294117647058823529411764705882352941176470…
From this, we can see that it has a repeating cycle of 16 digits: 0588235294117647. This means that once we reach the end of this sequence, it starts over again.
Finding the 300th Digit
To determine the 300th digit of this decimal, we first need to understand the repeating cycle. Since the sequence has a length of 16, we can use simple modular arithmetic to find the position of the 300th digit within the repeating cycle.
- Calculate the position: We can find the position of the 300th digit in the repeating cycle by using the formula:
[
\text{Position} = 300 \mod 16
]
Performing the calculation:
[
300 \div 16 = 18.75 \quad \text{(which gives us a remainder of 12)}
]
Therefore, (300 \mod 16 = 12). - Locate the digit: Now that we know the 300th digit corresponds to the 12th position in the repeating sequence, we can simply look at the decimal expansion:
- The repeating digits are: 0588235294117647.
- Counting to the 12th digit gives us: 4.
Thus, the 300th digit of the decimal representation of 0.0588235294117647 is 4.
