Question 985760: I am not certain what type of problem this is my daughter has so I hope I have selected the appropriate topic. My email address has been entered for the answer as well.
You are selling candy bars and sell 1/5 of them on the first day. You have 40 left. How many did you start with?
40 x 1/5
(multiply 5/5x 40 in order to get the common denominator) = 200/5 + 1/5 = 201/5
201/4 = 401/5
I hope that makes sense. Thanks Found 2 solutions by jim_thompson5910, MathTherapy:Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! The question asks "How many did you start with?" so let's make x equal to this unknown amount
x = original number of candy bars
We have x bars to start with and we sell 1/5 of them. So we sell x*(1/5) = x/5 candy bars. Subtract this from x to get

If you sold , then you're left with of what you began with
Now you can ask: " of what number gives me 40?"
Translated into mathematical terminology, and with N being number you began with, this becomes: of N = 40
4N = 200 ------------ Cross-multiplying
N, or number you started with = , or
