Answer 1

To convert the fraction \(\frac{711}{7}\) into a decimal, we can perform long division.

1. Long Division Calculation:

   • Divide 711 by 7.
   • 7 goes into 71 ten times (7 * 10 = 70), so write down 10.
   • Subtract 70 from 71, leaving 1.
   • Bring down the next digit (1), making it 11.
   • 7 goes into 11 once (7 * 1 = 7).
   • Subtract 7 from 11, leaving 4.
   • Bring down the next digit (0), making it 40.
   • 7 goes into 40 five times (7 * 5 = 35).
   • Subtract 35 from 40, leaving 5.
   • Bring down the next digit (0), making it 50.
   • 7 goes into 50 seven times (7 * 7 = 49).
   • Subtract 49 from 50, leaving 1.
   • Bring down another 0, making it 10.
   • 7 goes into 10 once (7 * 1 = 7).
   • Subtract 7 from 10, leaving 3.
   • Bring down another 0, making it 30.
   • 7 goes into 30 four times (7 * 4 = 28).
   • Subtract 28 from 30, leaving 2.
   • Bring down another 0, making it 20.
   • 7 goes into 20 two times (7 * 2 = 14).
   • Subtract 14 from 20, leaving 6.
   • Bring down another 0, making it 60.
   • 7 goes into 60 eight times (7 * 8 = 56).
   • Subtract 56 from 60, leaving 4.

   At this point, we recognize that we are repeating a previous calculation (with a remainder of 4). This indicates that the decimal will repeat.

2. Summary of the Division Results:

   • The whole number part is 101.
   • The decimal part that started repeating is \(142857\).

So, the entire division gives us:

\[ \frac{711}{7} = 101.142857\overline{142857} \]

3. Final Answer: The repeating decimal representation of \( \frac{711}{7} \) is:

\[ 101. \overline{142857} \]

This means that the digits \(142857\) repeat indefinitely.
