My son needs help with his math homework, but I don't know what to tell him! Can someone please clue me in?

Later on, in chemistry, you will learn that the correct way to do this is solute over total volume and in the interests of looking ahead, I think you should go that way. 5 apple parts / 13 parts total = 0.3846 3 apple parts / 9 parts total = 0.3333 6 apple parts / (9 + 6) = 6/15 = 0.4 3 / (5 + 3) = 3/8 = 0.375 That makes the third one the best choice. Since you have 2 methods, I think what you should do is look at the textbook to see which way it is done.

I will concede that this is not right, if the textbook shows the other method.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
