What is 2 7/13 as a decimal?

Answer

Fraction 2 7/13 as a decimal is

2.538461

≈ 2.54 to hundredths

Repeating decimal: denominator 13 has the factor 13, not 2 or 5 · the bar marks the period 538461 — 6 digits repeat forever

Whole part 2 stays in front; divide the fraction part:

remainder	×10	= digit × 13 + new remainder	digit
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
2	20	1 × 13 + 7	1

Remainder 7 is back after the 6th division → the 6 digits 538461 repeat: 0.538461.

2 + 0.538461 = 2.538461
