erik [133]

Step 1. Apply this rule: a ÷ $\frac{b}{c} =a* \frac{c}{b}$

$\frac{4}{5} * \frac{10}{3}$

Step 2. Apply this rule: $\frac{a}{b} * \frac{c}{d} = \frac{ac}{bd}$

$\frac{4*10}{5*3}$

Step 3. Simplify 4 × 10 to 40

$\frac{40}{5*3}$

Step 4. Simplify 5 × 3 to 15

$\frac{40}{15}$

Step 5. Simplify

$\frac{8}{3}$
