"<em>The product of 8 and a number increased by 4 is 60" </em>can be written as:
8y + 4 = 60
Your answer is A.
Not always if you're saying it will always be something like 1/2 becomes 2/1 with a unit of one. It's just flipped, so 2/6 will be 6/2, 4/5 becomes 5/4, 22/16 becomes 16/22 etc. That is all there is to it. Make sure you simplify your answers.
