a) First question I multiplied. For the second question I divided.
b)I multiplied 3.60x12=43.20 that is the price, then the second one I divided 3.60/2=1.80 then after I was done with that I divided the container into portions equally for both.
c) I could have used a ratio table for the questions.
d)I took 2 2/5 and multiplied it by 5. Then took the 12 and divided it by 2 which gave me the size of the cup. Then I did the same thing but only with the prices like the picture before.
