$$\frac{ 4 }{ 7 } - \frac{ 1 }{ 5 }$$

$\frac{13}{35}\approx 0.371428571$

Least common multiple of $7$ and $5$ is $35$. Convert $\frac{4}{7}$ and $\frac{1}{5}$ to fractions with denominator $35$.

$$\frac{20}{35}-\frac{7}{35}$$

Since $\frac{20}{35}$ and $\frac{7}{35}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{20-7}{35}$$
