Least common multiple of $4$ and $7$ is $28$. Convert $\frac{3}{4}$ and $\frac{2}{7}$ to fractions with denominator $28$.

$$\frac{21}{28}-\frac{8}{28}$$

Since $\frac{21}{28}$ and $\frac{8}{28}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{21-8}{28}$$

Subtract $8$ from $21$ to get $13$.

$$\frac{13}{28}$$

$\frac{13}{2 ^ {2} \cdot 7} = 0.4642857142857143$
