a. v:b:s, there is no definite answer because we do not know the value of these yogurts.
b.You cannot say how many times, the vanilla yogurt goes into the whole, because it will always end up being 1.something, so it is 3/5 to the whole ice cream. Take Strawberry being 2, the banana will be six, and vanilla 12. If you add the total which is 20, then the 12, we know 12 can fit into 20, so we make it a fraction! When we simplify 12/20, it becomes 3/5, you can plug that in with any other number, follow the formula and try it as well.
