    \[\frac{\frac{3}{4} \text{ mile }}{\frac{3}{5} \text{ hour }} =\frac{ ? \text{ mile }}{1 \text{ hour }}\] find the ? mark

    \[\frac{\frac{3}{4}}{\frac{3}{5}}=\frac{x}{1} \\ \text{ or } \frac{\frac{3}{4}}{\frac{3}{5}}=x\] you are just dividing 3/4 by 3/5

    can you try finishing from here? \[x=\frac{\frac{3}{4}}{\frac{3}{5}} \cdot \frac{\frac{5}{3}}{\frac{5}{3}}\] let me know what you get after trying to do this multiplication on top and bottom

    \[x=\frac{\frac{3}{4} \cdot \frac{5}{3}}{\frac{3}{5} \cdot \frac{5}{3}} \\ x=\frac{\frac{3(5)}{4(3)}}{\frac{3(5)}{5(3)}}\]

    hint 15/15 is just one anything divided by 1 is that anything \[x=\frac{3(5)}{4(3)}\]
