\( \frac{14}{11} \) as a decimal is \( 1.\overline{27} \).
Solución
1. We begin by writing the fraction as a division:
\[
\frac{14}{11} = 14 \div 11
\]
2. Since \(11\) goes into \(14\) one time, we have:
\[
1 \times 11 = 11
\]
\[
14 - 11 = 3 \quad \text{(remainder)}
\]
Thus, \( \frac{14}{11} = 1 + \frac{3}{11} \).
3. To convert the fractional part \(\frac{3}{11}\) into a decimal, we perform the division:
- Write \(3\) as \(3.000\ldots\) and divide by \(11\).
4. Dividing step-by-step:
- **Step 1:** \(11\) goes into \(30\) (after bringing down a \(0\)) \(2\) times because:
\[
2 \times 11 = 22
\]
Subtracting:
\[
30 - 22 = 8
\]
So far, the decimal is \(1.2\ldots\).
- **Step 2:** Bring down another \(0\) to the remainder \(8\) to get \(80\). \(11\) goes into \(80\) \(7\) times because:
\[
7 \times 11 = 77
\]
Subtracting:
\[
80 - 77 = 3
\]
Now, the decimal is \(1.27\ldots\).
- **Step 3:** The remainder is again \(3\). Repeating the process will yield the same sequence of digits (\(2\) then \(7\)).
5. We see the digits \(2\) and \(7\) repeat indefinitely. Therefore, the decimal representation is:
\[
1.\overline{27}
\]
Thus, \( \frac{14}{11} \) written as a decimal is \( 1.\overline{27} \).

The Deep Dive
To convert \( \frac{14}{11} \) into a decimal, you divide 14 by 11. Doing this gives you approximately 1.2727, which repeats. So, you can express it as \( 1.\overline{27} \) to indicate that "27" repeats indefinitely. This conversion from a fraction to a decimal not only helps in understanding the value better but also makes operations like addition or subtraction with decimals simpler in many contexts, especially in everyday scenarios like budgeting or shopping.
