1/2+5/14

Let's evaluate: $\frac{1}{2}+\frac{5}{14}$

ⓘ Add fractions by using a common denominator and then adding their numerators. We choose $14$, the least common multiple of $2$ and $14$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{1}{2}+\frac{5}{14}$ = $\frac{1\times 7}{2\times 7}+\frac{5}{14}$ = $\frac{1\times 7+5}{14}$ = $\frac{7+5}{14}$

$\frac{7+5}{14}$

ⓘ The numerator and the denominator are computed before the division: $7+5$ = $12$

$\frac{12}{14}$

ⓘ Simplify the fraction by dividing the numerator and the denominator by $2$, their greatest common divisor: $\frac{12}{14}$ = $\frac{6\times 2}{7\times 2}$ = $\frac{6}{7}$

▶Result:   $\frac{6}{7}$

The numeric value of: $\frac{6}{7}$ equals:

▷ $\approx 0.8571$
