What is 1 1/3 as a decimal?

Answer

Fraction 1 1/3 as a decimal is

1.3

≈ 1.33 to hundredths

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

Whole part 1 stays in front; divide the fraction part:

remainder	×10	= digit × 3 + new remainder	digit
1	10	3 × 3 + 1	3

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

1 + 0.3 = 1.3

Fraction 1 1/3 as a decimal is 1.(3)

To convert 1 1/3 to a decimal, divide the numerator by the denominator, 1 ÷ 3 = 0.(3), then add the whole part: 1 + 0.(3) = 1.(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: 1 1/3 ≈ 133.33%.
