2/7+9/14

Let's evaluate: $\frac{2}{7}+\frac{9}{14}$

ⓘ To add fractions, put them over the same denominator, then add the numerators. We choose $14$, the least common multiple of $7$ and $14$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{2}{7}+\frac{9}{14}$ = $\frac{2\times 2}{7\times 2}+\frac{9}{14}$ = $\frac{2\times 2+9}{14}$

$\frac{2\times 2+9}{14}$

ⓘ Multiplications are done before additions and subtractions: $2\times 2$ = $4$

$\frac{4+9}{14}$

ⓘ The numerator and the denominator are computed before the division: $4+9$ = $13$

▶Result:   $\frac{13}{14}$

The numeric value of: $\frac{13}{14}$ is:

▷ $\approx 0.9286$
