9/11 as a Decimal
9/11 = 0.8̅1̅
9/11 as a decimal is 0.8̅1̅ — the digits 81 repeat forever (≈ 0.818182).
Step by step
- Divide 9 by 11: 0 whole (so the answer starts 0.), remainder 9.
- Bring down a 0: 90 ÷ 11 = 8, remainder 2.
- Bring down a 0: 20 ÷ 11 = 1, remainder 9.
- Bring down a 0: 90 ÷ 11 = 8, remainder 2.
- Bring down a 0: 20 ÷ 11 = 1, remainder 9.
- Bring down a 0: 90 ÷ 11 = 8, remainder 2.
- Bring down a 0: 20 ÷ 11 = 1, remainder 9.
- Result: 9/11 = 0.8̅1̅ (repeating).
Why it repeats: after removing factors of 2 and 5, the denominator 11 still has the factor 11, so the division never ends and the remainders cycle. The repeating block “81” has 2 digits; round it to the precision you need, for example 0.82 or 0.8182.

How it works
A fraction means division: the numerator (top) divided by the denominator (bottom). Use long division, adding zeros after the decimal point until the remainder is zero or a remainder repeats. If the simplified denominator has only 2 and 5 as prime factors, the decimal terminates; otherwise it repeats forever, and the repeating digits are marked with a bar.
