What is 2 1/9 as a decimal?

Answer

Fraction 2 1/9 as a decimal is
2.1

≈ 2.11 to hundredths

Repeating decimal: denominator 9 = 3 × 3 has the factor 3, not 2 or 5 · the bar marks the period 1 — it repeats forever

2 1/9: whole part, then 1 ÷ 9

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

remainder×10= digit × 9 + new remainderdigit
1101 × 9 + 11

Remainder 1 is back after the 1st division → the digit 1 repeats forever: 0.1.

2 + 0.1 = 2.1
