The correct answer is B.

He had 2 1/2 liters of water.  He used 5/2 liters of water to make lemonade.

To convert 5/2 to a mixed number, see how many times 2 goes into 5.  It goes twice, so 2 is the whole number.  The remainder after dividing 5 by 2 is 1, so this is the numerator of the fraction; this gives us 2 1/2. 

This means he started with 2 1/2 liters of water and used 2 1/2 liters of it.  This leaves him 0 liters of water.

700a+1200r=1000000       (then plug in the a)
700(1000) +1200r=1000000        (simplify)
700000+1200r=1000000        (subtract 700000 from both sides)
1200r=300000             (divide by 1200 on both sides)
r=250
