Please don't freak when you read this question. It's easier than it looks (I think!). I am just dumb and not sure how to answer it.

My textbook doesn't explain this method and I don't have a teacher so I'm stuck.

(3/8y + 5/6x) / (5/12xy)

The answer is:

(9x + 20y) / 10

I am not sure how to add two fractions that have completely different denominators. How did they do this?

Can anyone help me, please?

Thanks!
