Answer 1

Steve,

 

Since the ratio of concentrate to water will be the same no matter how much of the drink you have, set up a proportion like this:

 

5/8 = x/y (where x is the new amount of concentrate and y is the water you need)

 

So 8x = 5y

 

Then start picking x's:

 

e.g.,

 

x  y

1  8/5

2  16/5

3  24/5

4  32/5

5  8

6  48/5

7  56/5

 

etc.
