Verified Answer :

This question is based on greatest common multiple.

Answer:

Cynthia is right that Andy made an error.

Step-by-step explanation:

As per Andy, action dvds are = \(\frac{3}{5}\)

And comedy dvd's are = \(\frac{1}{4}\)

So, in total these become = \(\frac{3}{5}+ \frac{1}{4}\)

= \(\frac{12+5}{20}\) = \(\frac{17}{20}\)

This is not 4/9 as per Andy.
