Try applying the rule of division: x/y=x*(1/y)

3. anonymous

hmmm

4. imqwerty

If we are given (a/b) /(c/d) we can say that we have - a/b x d/c

5. anonymous

All together i would get 1/60 but that is not an answer choice

6. phi

notice this idea: $\frac{ \frac{1}{2}}{\frac{5}{8} }$ multiply top and bottom by the same thing: 8/5 $\frac{ \frac{1}{2}\cdot \frac{8}{5}}{\frac{5}{8}\cdot \frac{8}{5} }$ now simplify top and bottom

7. phi

the bottom becomes 1 and dividing by 1 can be ignored. we just have the top (simplified)

8. anonymous

4/5

9. phi

yes. the idea I posted is usually simplified to the rule multiply the top by the "flipped" bottom
