You have a 2 litre jug of 3.5% milk (milk that contains 3.5% fat). how much skim milk (0% fat) do you need to add to it to obtain milk which will have 2% fat?

Total amount of skim milk needed to be added = 0.83 liters

Step-by-step explanation:

Required fat in the resultant milk = 2%

Current amount of fat in the milk = 3.5%

So, 1 - 0.57 = 0.43 liters of skim milk to be added per liter to make the quantity of fat 2% in the whole milk.

Quantity of milk present = 2 liters

So, total amount of skim milk needed to be added = 2 × 0.43

                                                                                       = 0.83 liters

the answer is 0.071

good luck! : d

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
