Fraction $\frac{-5}{7}$ can be rewritten as $-\frac{5}{7}$ by extracting the negative sign.

$$\frac{3}{4}-\frac{5}{7}$$

Least common multiple of $4$ and $7$ is $28$. Convert $\frac{3}{4}$ and $\frac{5}{7}$ to fractions with denominator $28$.

$$\frac{21}{28}-\frac{20}{28}$$

Since $\frac{21}{28}$ and $\frac{20}{28}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{21-20}{28}$$

Subtract $20$ from $21$ to get $1$.

$$\frac{1}{28}$$

$\frac{1}{2 ^ {2} \cdot 7} = 0.03571428571428571$
