$$\frac { 4 } { 5 } + \frac { 6 } { 7 } + \frac { 1 } { 2 }$$

$\frac{151}{70}\approx 2.157142857$

Least common multiple of $5$ and $7$ is $35$. Convert $\frac{4}{5}$ and $\frac{6}{7}$ to fractions with denominator $35$.

$$\frac{28}{35}+\frac{30}{35}+\frac{1}{2}$$

Since $\frac{28}{35}$ and $\frac{30}{35}$ have the same denominator, add them by adding their numerators.

$$\frac{28+30}{35}+\frac{1}{2}$$

Add $28$ and $30$ to get $58$.

$$\frac{58}{35}+\frac{1}{2}$$

Least common multiple of $35$ and $2$ is $70$. Convert $\frac{58}{35}$ and $\frac{1}{2}$ to fractions with denominator $70$.

$$\frac{116}{70}+\frac{35}{70}$$

Since $\frac{116}{70}$ and $\frac{35}{70}$ have the same denominator, add them by adding their numerators.

$$\frac{116+35}{70}$$

Add $116$ and $35$ to get $151$.

$$\frac{151}{70}$$

$\frac{151}{2 \cdot 5 \cdot 7} = 2\frac{11}{70} = 2.157142857142857$
