Equal amounts of water poured into two empty jars of different capacities, which made one jar 1/4 full and the other jar 1/3 full. If the water in teh jar with the lesser capacity is then poured into the jar with the greater capacity, what fraction of the larger jar will be filled with water?

1/7
2/7
1/2
7/12
2/3

The larger jar is the one which is "less" full. In this case, the larger
jar is the one that is 1/4 full. Since equal amounts of water are poured
into each of the 2 jars, the larger one will become 1/4 + 1/4 = 1/2 full

So, answer = 1/2

You can also try picking numbers, sometimes that makes it go faster. Say that each amount of liquid is 4 so you would have 4/12 and 4/16 respectively pour the 4 into the 4/16 and you have 8/16 or 1/2. Jay's answer is probably more succint but this helps me visualize a little better.
