I need help Can't figure it out

1. what we can do is find the Least Common Factos of both 4 and 3 which is 12

so we start with a contanier or 12/12 then her brother drinks 1/4 which is also 3/12 and her dad drinks 2/3 or 8/12 of the remaining 9/12 so in the end we are left with 1/12

2. we will do the same thing she has 12/12 her sister drinks 1/3 or 4/12 then her mother drinks 3/4 which also 9/12 of 2/3 which is also 8/12. I think we are also counting the amount left from the day before so in the end all of the lemonade is drank none is left of both containers
