What is 3 2/13 as a decimal?

Answer

Fraction 3 2/13 as a decimal is

3.153846

≈ 3.15 to hundredths

Repeating decimal: denominator 13 has the factor 13, not 2 or 5 · the bar marks the period 153846 — 6 digits repeat forever

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

remainder	×10	= digit × 13 + new remainder	digit
2	20	1 × 13 + 7	1
7	70	5 × 13 + 5	5
5	50	3 × 13 + 11	3
11	110	8 × 13 + 6	8
6	60	4 × 13 + 8	4
8	80	6 × 13 + 2	6

Remainder 2 is back after the 6th division → the 6 digits 153846 repeat: 0.153846.

3 + 0.153846 = 3.153846

In lowest terms its denominator 13 has the prime factor 13, so the division never ends: a remainder comes back and the same digits repeat forever.
