Step-by-step solution

The problem

\frac{2}{4}

  1. Divide 2 by 4 (long division). Write down how many times 4 goes in, carry the remainder, add a 0 and divide again. The remainder is 0, so the decimal ends here.

    StepDivideDigitRemainderWorking
    Whole part2 ÷ 4024 × 0 = 0, 2 − 0 = 2
    Decimal place 120 ÷ 4504 × 5 = 20, 20 − 20 = 0

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

    = 2 \div 4 = \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{2}{4} \\[8pt] &= 2 \div 4 && \textcolor{#5b6660}{\textsf{divide}} \\[8pt] &= \textcolor{#0b5c56}{0.5}\end{aligned}
