7/9-1/12

Let's calculate: $\frac{7}{9}-\frac{1}{12}$

ⓘ To add fractions, put them over the same denominator, then add the numerators. We choose $36$, the least common multiple of $9$ and $12$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{7}{9}-\frac{1}{12}$ = $\frac{7\times 4}{9\times 4}-\frac{1\times 3}{12\times 3}$ = $\frac{7\times 4-1\times 3}{9\times 4}$

$\frac{7\times 4-1\times 3}{9\times 4}$

ⓘ Perform multiplications before additions and subtractions: $7\times 4$ = $28$, $1\times 3$ = $3$

ⅰ $9\times 4$ = $36$

$\frac{28-3}{36}$

ⓘ Calculate the numerator and denominator before dividing: $28-3$ = $25$

▶Result:   $\frac{25}{36}$

The numeric value of: $\frac{25}{36}$ is:

▷ $\approx 0.6944$
