Andy has a collection of movie dvds. in andys collection 3/5 of the dvds are action 1/4 of the dvds are comedy. andy said that 4/9 of his collection is action or comedy. cynthia said that andy made an errer. explain wether andy is correct or incorect and why what fraction of the dvds in andys collection is not "action" or "comedy"​

Andy is not correct because whenadding the 2 fractions, he needsto create fractional parts with thesame denominator. NOTHINGcan be added unless the units arethe same. The denominator of afraction are the units. He neededto make 3/5 12/20 and 1/4 5/20Adding these together would be17/20, making 3/20 of them NOTaction or comedy.17/20+3/2020/20 or the total.

I hope it helps

have a great day

Cynthia is right that Andy made an error.

Step-by-step explanation:

As per Andy, action dvds are = 3/5

And comedy dvd's are = 1/4

So, in total these become = 3/5+1/4

= 12+5/20

= 17/20

This is not 4/9 as per Andy.
