Jane had a bottle filled with juice. At first, she drank 1/5 of the juice in the bottle. After 1 hour, she drank 1/4 of the juice remaining in the bottle. After another 2 hours, she drank 1/3 of the remaining juice in the bottle. At that point, Jane checked how much juice was left: There was 2/3 of a cup left. How much juice was in the bottle originally?

ok... so she drank 1/5                    

so 4/5 remaining... so 1/4 of 4/5 = 1/5

so 3/5 remaining then 1/3 of 3/5 = 1/5 

so there is 3/5 been drunk and 2/5 remaining....

so 

2/5 = 2/3 of a cup... 

or dividing by 2 to find the measure of 1/5 

1/5 = 1/3 of a cup 

then 5 lots of 1/5 =  5 * 1/3   

the the drink contained 5/3 or   1 and 2/3 cups 

hope it makes sense
