One does not simply swap the fractions whenever he or she feels like it!

addition is commutative, but subtraction is not.

@headge  Do you understand negative numbers? So, in this example it's okay for the answer to be less than zero, or rewrite it as @Agent47 has done.

Why is the 57y now over 50?

To answer your question, you need to simplify the issue. You need to put y/40 outside the brackets and the remaining numbers inside the brackets. Then you will see that 2057 is definitely not the same value as 5720

Now *that's* an excellent example there @MarkRijckenberg @headge  I'd be careful about how I interact with the people who are helping you, ok? Now, what part of this problem don't you understand? Did Mark's example help?

Y/2  5y/8 + 4y/5 = 20y/40  25y/40 + 32y/40 = 20y/40  57y/40 Then I got stuck. What do you mean? What have I said that is rude?

Hmm, so now I'm confused. Are you supposed to solve for y in this problem? In terms of your original question, are you able to do that part? 20  57 = ?

Ok, understood. So, are you able to subtract 20y from 57y? An easier way to think of it is by adding a negative, as @Agent47 did. So, 57 + 20 = ? (this answer will be a negative number FYI)

I disagree: Y/2  5y/8 + 4y/5 = 20y/40  25y/40 + 32y/40 = 5y/40 + 32y/40 = 27y/40
