Step-by-step solution

The problem

\frac{8}{10}

  1. Divide 8 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 part8 ÷ 100810 × 0 = 0, 8 − 0 = 8
    Decimal place 180 ÷ 108010 × 8 = 80, 80 − 80 = 0

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

    = 8 \div 10 = \textcolor{#0b5c56}{0.8}

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

    \frac{4}{5} = \frac{4 \times 2}{5 \times 2} = \frac{8}{10} = 0.8

All the working together

\begin{aligned} &\frac{8}{10} \\[8pt] &= 8 \div 10 && \textcolor{#5b6660}{\textsf{divide}} \\[8pt] &= \textcolor{#0b5c56}{0.8}\end{aligned}
