Step-by-step solution

The problem

\frac{4}{15}

  1. Divide 4 by 15 (long division). Write down how many times 15 goes in, carry the remainder, add a 0 and divide again. The remainder 10 came back, so the digits from decimal place 2 on repeat forever.

    StepDivideDigitRemainderWorking
    Whole part4 ÷ 150415 × 0 = 0, 4 − 0 = 4
    Decimal place 140 ÷ 1521015 × 2 = 30, 40 − 30 = 10
    Decimal place 2100 ÷ 1561015 × 6 = 90, 100 − 90 = 10

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

    = 4 \div 15 = \textcolor{#0b5c56}{0.2\overline{6}}

All the working together

\begin{aligned} &\frac{4}{15} \\[8pt] &= 4 \div 15 && \textcolor{#5b6660}{\textsf{divide}} \\[8pt] &= \textcolor{#0b5c56}{0.2\overline{6}}\end{aligned}
