500:75
x:100
to get from 75 to 25 you can..
divide by 3 then times by 4
so you do the same with 500 to get x
500/3=166.666...
166.666...x4=668 rounded up
that may be it

hey katie does it work if i do this:
500/75= .15 of ppl like oranges
100-75= 25 more ppl we need to find that like oranges
25/.15= 166?
