1/2+13/20

Let's evaluate: $\frac{1}{2}+\frac{13}{20}$

ⓘ To add fractions, put them over the same denominator, then add the numerators. We choose $20$, the least common multiple of $2$ and $20$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{1}{2}+\frac{13}{20}$ = $\frac{1\times 10}{2\times 10}+\frac{13}{20}$ = $\frac{1\times 10+13}{20}$ = $\frac{10+13}{20}$

$\frac{10+13}{20}$

ⓘ Calculate the numerator and denominator before dividing: $10+13$ = $23$

▶Result:   $\frac{23}{20}$

The numeric value of: $\frac{23}{20}$ is:

▷ $1.15$
