2/3 = 0.6̅

2/3 as a decimal is 0.6̅ — the digit 6 repeat forever (≈ 0.666667).

Step by step

  1. Divide 2 by 3: 0 whole (so the answer starts 0.), remainder 2.
  2. Bring down a 0: 20 ÷ 3 = 6, remainder 2.
  3. Bring down a 0: 20 ÷ 3 = 6, remainder 2.
  4. Bring down a 0: 20 ÷ 3 = 6, remainder 2.
  5. Bring down a 0: 20 ÷ 3 = 6, remainder 2.
  6. Bring down a 0: 20 ÷ 3 = 6, remainder 2.
  7. Bring down a 0: 20 ÷ 3 = 6, remainder 2.
  8. Result: 2/3 = 0.6̅ (repeating).

Why it repeats: after removing factors of 2 and 5, the denominator 3 still has the factor 3, so the division never ends and the remainders cycle. The repeating block “6” has 1 digit; round it to the precision you need, for example 0.67 or 0.6667.

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.
