Question

(\frac{3}{5})比(z=\frac{4}{7})

Explanation:

Step1: Rewrite division as multiplication

$\frac{3}{5}z=\frac{4}{7} \implies z=\frac{4}{7} \times \frac{5}{3}$

Step2: Multiply numerators and denominators

$z=\frac{4 \times 5}{7 \times 3}$

Step3: Calculate the product

$z=\frac{20}{21}$

Answer:

$z=\frac{20}{21}$
