1 whole + 3 of 7 equal parts

Step-by-step solution

The problem

\frac{10}{7}

  1. Divide 10 by 7 (long division). Write down how many times 7 goes in, carry the remainder, add a 0 and divide again. The remainder 3 came back, so the digits from decimal place 1 on repeat forever.

    StepDivideDigitRemainderWorking
    Whole part10 ÷ 7137 × 1 = 7, 10 − 7 = 3
    Decimal place 130 ÷ 7427 × 4 = 28, 30 − 28 = 2
    Decimal place 220 ÷ 7267 × 2 = 14, 20 − 14 = 6
    Decimal place 360 ÷ 7847 × 8 = 56, 60 − 56 = 4
    Decimal place 440 ÷ 7557 × 5 = 35, 40 − 35 = 5
    Decimal place 550 ÷ 7717 × 7 = 49, 50 − 49 = 1
    Decimal place 610 ÷ 7137 × 1 = 7, 10 − 7 = 3

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

    = 10 \div 7 = \textcolor{#0b5c56}{1.\overline{428571}}
