Answer:
Each classroom gets exactly 46 oz.
Step-by-step explanation:
In order to find that, start by converting the amount to oz. We can do this by multiplying the amount of pounds by 16 and then adding the ounces.
8 * 16 = 128
128 + 10 = 138 oz
Now we can divide that amount by 3 to get the amount per classroom.
138/3 = 46 oz per classroom.
