Question

$$\frac{ 12 }{ 13 } + \frac{ 11 }{ 17 }$$

Evaluate

$\frac{347}{221}\approx 1.570135747$

Solution Steps

Least common multiple of $13$ and $17$ is $221$. Convert $\frac{12}{13}$ and $\frac{11}{17}$ to fractions with denominator $221$.

$$\frac{204}{221}+\frac{143}{221}$$

Since $\frac{204}{221}$ and $\frac{143}{221}$ have the same denominator, add them by adding their numerators.

$$\frac{204+143}{221}$$

Add $204$ and $143$ to get $347$.

$$\frac{347}{221}$$

Factor

$\frac{347}{13 \cdot 17} = 1\frac{126}{221} = 1.5701357466063348$
