3/4-5/14

Let's evaluate: $\frac{3}{4}-\frac{5}{14}$

ⓘ Add fractions by using a common denominator and then adding their numerators. We choose $28$, the least common multiple of $4$ and $14$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{3}{4}-\frac{5}{14}$ = $\frac{3\times 7}{4\times 7}-\frac{5\times 2}{14\times 2}$ = $\frac{3\times 7-5\times 2}{4\times 7}$

$\frac{3\times 7-5\times 2}{4\times 7}$

ⓘ Perform multiplications before additions and subtractions: $3\times 7$ = $21$, $5\times 2$ = $10$

ⅰ $4\times 7$ = $28$

$\frac{21-10}{28}$

ⓘ Calculate the numerator and denominator before dividing: $21-10$ = $11$

▶Result:   $\frac{11}{28}$

The numeric value of: $\frac{11}{28}$ is:

▷ $\approx 0.3929$
