The ratio of frozen concentrate to water is 1 to 3 how much water and how much frozen concentrate are needed for 2 liters of juice

Question

The ratio of frozen  concentrate  to  water  for most juices is 1 to 3 how much water and frozen  concentrate  are needed  to make 2 liters of juice

Answer 1

Assuming that nothing strange happens to the volume of the concentrate as it thaws, the equations for solving this problem can look like this:

 

frozen concentrate / water = 1 / 3

 

frozen concentrate + water = 2 liters

 

Now just solve for the two variables.
