$$\frac{3}{4}+\frac{5}{6}-\frac{7}{8}$$

$\frac{17}{24}\approx 0.708333333$

Least common multiple of $4$ and $6$ is $12$. Convert $\frac{3}{4}$ and $\frac{5}{6}$ to fractions with denominator $12$.

$$\frac{9}{12}+\frac{10}{12}-\frac{7}{8}$$

Since $\frac{9}{12}$ and $\frac{10}{12}$ have the same denominator, add them by adding their numerators.

$$\frac{9+10}{12}-\frac{7}{8}$$

Add $9$ and $10$ to get $19$.

$$\frac{19}{12}-\frac{7}{8}$$

Least common multiple of $12$ and $8$ is $24$. Convert $\frac{19}{12}$ and $\frac{7}{8}$ to fractions with denominator $24$.

$$\frac{38}{24}-\frac{21}{24}$$

Since $\frac{38}{24}$ and $\frac{21}{24}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{38-21}{24}$$

Subtract $21$ from $38$ to get $17$.

$$\frac{17}{24}$$

$\frac{17}{2 ^ {3} \cdot 3} = 0.7083333333333334$
