ⓘ To add fractions, put them over the same denominator, then add the numerators. We choose

70

, the least common multiple of

7

and

10

. Multiplying the numerator and the denominator by the same number does not change the fraction:

\frac{1}{7} + \frac{1}{10}

\frac{1 \times 10}{7 \times 10} + \frac{1 \times 7}{10 \times 7}

\frac{1 \times 10 + 1 \times 7}{7 \times 10}

\frac{10 + 7}{7 \times 10}

18 + \frac{10 + 7}{7 \times 10}

ⓘ The numerator and the denominator are computed before the division:

10 + 7
