What is 3 3/9 as a decimal?

Answer

Fraction 3 3/9 as a decimal is

3.3

≈ 3.33 to hundredths

Repeating decimal: 3/9 = 1/3 · denominator 3 has the factor 3, not 2 or 5 · the bar marks the period 3 — it repeats forever

Whole part 3 stays in front; divide the fraction part:

remainder	×10	= digit × 9 + new remainder	digit
3	30	3 × 9 + 3	3

Remainder 3 is back after the 1st division → the digit 3 repeats forever: 0.3.

3 + 0.3 = 3.3

Fraction 3 3/9 as a decimal is 3.(3)

To convert 3 3/9 to a decimal, divide the numerator by the denominator, 3 ÷ 9 = 0.(3), then add the whole part: 3 + 0.(3) = 3.(3).

In lowest terms its denominator 3 has the prime factor 3, so the division never ends: a remainder comes back and the same digits repeat forever.

Multiply by 100: 3 3/9 ≈ 333.33%.
