4/9 as a Decimal
4/9 = 0.4̅
4/9 as a decimal is 0.4̅ — the digit 4 repeat forever (≈ 0.444444).
Step by step
- Divide 4 by 9: 0 whole (so the answer starts 0.), remainder 4.
- Bring down a 0: 40 ÷ 9 = 4, remainder 4.
- Bring down a 0: 40 ÷ 9 = 4, remainder 4.
- Bring down a 0: 40 ÷ 9 = 4, remainder 4.
- Bring down a 0: 40 ÷ 9 = 4, remainder 4.
- Bring down a 0: 40 ÷ 9 = 4, remainder 4.
- Bring down a 0: 40 ÷ 9 = 4, remainder 4.
- Result: 4/9 = 0.4̅ (repeating).
Why it repeats: after removing factors of 2 and 5, the denominator 9 still has the factor 9, so the division never ends and the remainders cycle. The repeating block “4” has 1 digit; round it to the precision you need, for example 0.44 or 0.4444.

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.
