11/20+1/10

Let's calculate: $\frac{11}{20}+\frac{1}{10}$

ⓘ Add fractions by using a common denominator and then adding their numerators. We choose $20$, the least common multiple of $20$ and $10$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{11}{20}+\frac{1}{10}$ = $\frac{11}{20}+\frac{1\times 2}{10\times 2}$ = $\frac{11+1\times 2}{20}$ = $\frac{11+2}{20}$

$\frac{11+2}{20}$

ⓘ The numerator and the denominator are computed before the division: $11+2$ = $13$

▶Result:   $\frac{13}{20}$

The numeric value of: $\frac{13}{20}$ equals:

▷ $0.65$
