~Hope this helps! Sorry if my answer is confusing at all, it's pretty difficult to explain.~
Let's assume you have supplement angle

Now when you talk about multiplication you can simply say...

And that will give you the answer.
If you have two equivalent fraction and you want to add them it depends on if they have the same denominator if they don't you find the common denominator then how much it can go in the denominator you times it by the numerator and if then answer that you get can be reduced you reduce it.
