Answer:
Choise B: 
Step-by-step explanation:
For this exercise you must remember the multiplication of signs:

By definition, equivalent expression have the same value.
Then, you can find an equivalent expression to the expression provided in the exercise by simplifying it.
So, given:

To simplify it, you can distribute the negative that is located outside of the parentheses (in order to eliminate the parentheses).
Applying this procedure, you get the following equivalent expression:

Therefore, as you can notice, the expression obtained matches with the one shown in Choice B.
All you need to do is put 45 over 100 to make it 45/100, then simplify down until you get your answer. The answer is 9/20 though. There may be better ways, but that's how I do it.
