Step-by-step solution

The problem

\frac{5}{10}

  1. Divide 5 by 10 (long division). Write down how many times 10 goes in, carry the remainder, add a 0 and divide again. The remainder is 0, so the decimal ends here.

    StepDivideDigitRemainderWorking
    Whole part5 ÷ 100510 × 0 = 0, 5 − 0 = 5
    Decimal place 150 ÷ 105010 × 5 = 50, 50 − 50 = 0

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

    = 5 \div 10 = \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{5}{10} \\[8pt] &= 5 \div 10 && \textcolor{#5b6660}{\textsf{divide}} \\[8pt] &= \textcolor{#0b5c56}{0.5}\end{aligned}
