Step-by-step solution

The problem

\frac{11}{30}

  1. Divide 11 by 30 (long division). Write down how many times 30 goes in, carry the remainder, add a 0 and divide again. The remainder 20 came back, so the digits from decimal place 2 on repeat forever.

    StepDivideDigitRemainderWorking
    Whole part11 ÷ 3001130 × 0 = 0, 11 − 0 = 11
    Decimal place 1110 ÷ 3032030 × 3 = 90, 110 − 90 = 20
    Decimal place 2200 ÷ 3062030 × 6 = 180, 200 − 180 = 20

  2. Read off the decimal. A bar over digits means they repeat forever.

    = 11 \div 30 = \textcolor{#0b5c56}{0.3\overline{6}}
