Sam picked 1/2 gallon of blue berries. Sam poured the blueberries into one of his plastic containers and noticed that the berries filled the container 2/3 full. solve the following problems in any way you like without using the calculator, and explain your reasoning in detail:

A.how many of Sam containers will 1 gallon of blueberries fill? (assume that Sam has a number of containers of the same size)

B.how many gallon of blueberries does it take to fill Sam container completely full?

this is what i have done:

for A.

i did 1÷1\2=2

then 2x2\3 which gave me 4/3

and for B.

I just did 1/2x2/3 which gave me 1/3, but I'm not sure if i suppose to multiply.
