Step-by-step solution

The problem

\frac{4}{8}

  1. Divide 4 by 8 (long division). Write down how many times 8 goes in, carry the remainder, add a 0 and divide again. The remainder is 0, so the decimal ends here.

    StepDivideDigitRemainderWorking
    Whole part4 ÷ 8048 × 0 = 0, 4 − 0 = 4
    Decimal place 140 ÷ 8508 × 5 = 40, 40 − 40 = 0

  2. Read off the decimal. The digits are read from the Digit column.

    = 4 \div 8 = \textcolor{#0b5c56}{0.5}

  3. Check with a shortcut. The denominator 2 can be made 10 by multiplying by 5, so the decimal ends after 1 place.

    \frac{1}{2} = \frac{1 \times 5}{2 \times 5} = \frac{5}{10} = 0.5

All the working together

\begin{aligned} &\frac{4}{8} \\[8pt] &= 4 \div 8 && \textcolor{#5b6660}{\textsf{divide}} \\[8pt] &= \textcolor{#0b5c56}{0.5}\end{aligned}
