7/10+5/11

Let's calculate: $\frac{7}{10}+\frac{5}{11}$

ⓘ Add fractions by using a common denominator and then adding their numerators. We choose $110$, the least common multiple of $10$ and $11$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{7}{10}+\frac{5}{11}$ = $\frac{7\times 11}{10\times 11}+\frac{5\times 10}{11\times 10}$ = $\frac{7\times 11+5\times 10}{10\times 11}$

$\frac{7\times 11+5\times 10}{10\times 11}$

ⓘ Perform multiplications before additions and subtractions: $7\times 11$ = $7\times (10+1)$ = $7\times 10+7$ = $70+7$ = $77$, $5\times 10$ = $50$

ⅰ $10\times 11$ = $10\times (10+1)$ = $10\times 10+10$ = $100+10$ = $110$

$\frac{77+50}{110}$

ⓘ The numerator and the denominator are computed before the division: $77+50$ = $127$

▶Result:   $\frac{127}{110}$

The numeric value of: $\frac{127}{110}$ equals:

▷ $\approx 1.1545$
