What is 13/3 as a decimal?

Answer

Fraction 13/3 as a decimal is

4.3

≈ 4.33 to hundredths

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

13 = 4 × 3 + 1: whole part 4, then divide the remainder 1

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.

4 + 0.3 = 4.3

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.
