What is 1 4/13 as a decimal?

Answer

Fraction 1 4/13 as a decimal is

1.307692

≈ 1.31 to hundredths

Repeating decimal: denominator 13 has the factor 13, not 2 or 5 · the bar marks the period 307692 — 6 digits repeat forever

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

remainder	×10	= digit × 13 + new remainder	digit
4	40	3 × 13 + 1	3
1	10	0 × 13 + 10	0
10	100	7 × 13 + 9	7
9	90	6 × 13 + 12	6
12	120	9 × 13 + 3	9
3	30	2 × 13 + 4	2

Remainder 4 is back after the 6th division → the 6 digits 307692 repeat: 0.307692.

1 + 0.307692 = 1.307692
