Answer:
4 cups of milk chocolate
Step-by-step explanation:
if there are 6 cups in total, then you can see that 1:2 is equal to 3 cups in total. If you multiply both sides of the ratio by 2, then you get 2:4, which is 6. You have to add the chocolate together to find how much it equals in total. Because it's white chocolate to milk chocolate, that would be 2:4, so there are 4 cups of milk chocolate.
Answer:

Step-by-step explanation:
Let the first number is x1 and other number is y1 then

Therefore


also there sum is
....Eq(1)
Putting the value of y1 in the previous equation
........Eq(2)
Differentiate the the Eq(2) with respect to x1 we get



Putting the value of X1 in Eq(1) we get

So 
It’s b
it’s not A because it’s not percentages it’s decimals using boxes as an example
