Solution Steps

Express $\frac{\frac{8}{1}}{2}$ as a single fraction.

$$\frac{8}{2}-\frac{\frac{2}{5}}{8}$$

Divide $8$ by $2$ to get $4$.

$$4-\frac{\frac{2}{5}}{8}$$

Express $\frac{\frac{2}{5}}{8}$ as a single fraction.

$$4-\frac{2}{5\times 8}$$

Multiply $5$ and $8$ to get $40$.

$$4-\frac{2}{40}$$

Reduce the fraction $\frac{2}{40}$ to lowest terms by extracting and canceling out $2$.

$$4-\frac{1}{20}$$

Convert $4$ to fraction $\frac{80}{20}$.

$$\frac{80}{20}-\frac{1}{20}$$

Since $\frac{80}{20}$ and $\frac{1}{20}$ have the same denominator, subtract them by subtracting their numerators.
