Part A) the first and the third answer are equivalent because.

n+n+n+n+2= 4n+2 which is the same as the third answer.

Part B) 2 and 4 are not equivalent because

2) n+n+n+2= 3n+2

4) 2n+2n+2n= 6n

as we can see they are not the same. Therefore they are not equivalent.

hope this helps

Five is a common factor that goes into both 10 and 25
10 divided by 5 is 2
25 divided by 5 is 5
So since there are no more common factors to simplify your fraction 2/5 is your answer
