The correct Answer is:
To find the decimal representation of the fraction \( \frac{8}{11} \), we will perform long division. Here’s a step-by-step solution: ### Step 1: Set up the division We need to divide 8 by 11. Since 8 is less than 11, we will place a decimal point and add a zero to 8, making it 80. ### Step 2: Determine how many times 11 fits into 80 11 goes into 80 a total of 7 times because \( 11 \times 7 = 77 \). ### Step 3: Subtract to find the remainder Now, we subtract 77 from 80: \[ 80 - 77 = 3 \] So, we have a remainder of 3. ### Step 4: Bring down another zero Next, we bring down another zero, making it 30. ### Step 5: Determine how many times 11 fits into 30 11 goes into 30 a total of 2 times because \( 11 \times 2 = 22 \). ### Step 6: Subtract to find the new remainder Now, we subtract 22 from 30: \[ 30 - 22 = 8 \] So, we have a remainder of 8 again. ### Step 7: Repeat the process We bring down another zero, making it 80 again. We see that we are back to where we started. ### Step 8: Identify the repeating pattern Since we previously found that 11 goes into 80 a total of 7 times, we can see that the decimal will repeat. Thus, the decimal representation of \( \frac{8}{11} \) is: \[ 0.727272\ldots \] We can express this as \( 0.\overline{72} \), indicating that "72" repeats indefinitely. ### Final Answer The decimal representation of \( \frac{8}{11} \) is \( 0.\overline{72} \). ---
