7/12+14/15

Let's evaluate: $\frac{7}{12}+\frac{14}{15}$

ⓘ Add fractions by using a common denominator and then adding their numerators. We choose $60$, the least common multiple of $12$ and $15$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{7}{12}+\frac{14}{15}$ = $\frac{7\times 5}{12\times 5}+\frac{14\times 4}{15\times 4}$ = $\frac{7\times 5+14\times 4}{12\times 5}$

$\frac{7\times 5+14\times 4}{12\times 5}$

ⓘ Multiplications are done before additions and subtractions: $7\times 5$ = $35$, $14\times 4$ = $(10+4)\times 4$ = $10\times 4+4\times 4$ = $40+16$ = $56$

ⅰ $12\times 5$ = $(10+2)\times 5$ = $10\times 5+2\times 5$ = $50+10$ = $60$

$\frac{35+56}{60}$

ⓘ Calculate the numerator and denominator before dividing: $35+56$ = $91$

▶Result:   $\frac{91}{60}$

The numeric value of: $\frac{91}{60}$ is:

▷ $\approx 1.5167$
