Step-by-step explanation:
12-(-6)=18
-18+12=-6
If you want 3/4 in 64's, multiply the numerator (3) by 16, as 4 x 16 = 64.

The probability model
To do this, we simply calculate the probability of each container.
So, we have:





So, the probability model is:

First let's start with the relationship between grams and centigrams and grams and milligrams.
1 gram = 100 centigrams
1 gram = 1000 milligrams
Because these two equations are equal, we can rewrite our equation as 100 centigrams = 1000 milligrams.
Now we divide by 100 to simplify our equation to 1 centigram = 10 milligrams.
With this simplified equation we see that we multiply the number of centigrams by 10 to find the equal number of milligrams.
