Answer:
Ming must add 0.375 L of a 10% sugar solution
Step-by-step explanation:
if 3 L = 80%
1.5 L should = 40% (since it is half of 80%)
and if 40 divided by 4 = 10%
1.5 also needs to be divided by 4
so 1.5 divided by 4 = 0.375
that means Ming must add 0.375 L of a 10% sugar solution
-15 is 15 below o
you are adding 4 , so you are getting closer to 0
so you would actually use subtraction, 15-4 = 11
since 15 is negative, and you are adding a number smaller than 15, the answer would be negative so it would be -11
What are you trying to figure out??
We know to each pound of such, there is 16 packets produced per?
So, 16 x 40 = 640.
