A logistics coordinator for a shipping company uses the proportion $\frac{n}{10} = \frac{3}{5}$ to determine the number of delivery trucks ($n$) needed for 10 regional routes. According to the method of cross-multiplication, which equation represents the correct first step to obtain a fraction-free equation?

A logistics manager uses the proportion $\frac{T}{24} = \frac{5}{8}$ to determine the number of trailers ($T$) required for a shipment. Match each component of the cross-multiplication process to its correct partner or function in creating a fraction-free equation.

A logistics coordinator is scaling a shipping plan using the proportion $\frac{r}{12} = \frac{5}{3}$, where $r$ represents the required number of regional hubs. Arrange the steps of the cross-multiplication process in the correct order to convert this proportion into a fraction-free equation.
