Answer:
111-(9*12)=3.
Explanation:
There are 111 ounces of orange paint, which is going to go into the other bottles. How many bottles? 9. However, because in life we have different sized bottles, it states each bottle takes 12 ounces. In order to find the amount of ounces needed to find all 9 bottles, we first multiply 9*12, which equals 108. Filling all the bottles with orange paint will take up 108 ounces of the orange paint. We do have enough, since we have 111 ounces, but we must find how many ounces we have now that we've used up 108, which can be done by subtraction. 111-108=3. We have 3 ounces left over.
Now we translate everything we did into a mathematical equation. First, we multiplied, and then we subtracted the product from 111. 111-(9*12), which equaled 3, so 111-(9*12)=3. The parentheses technically aren't necessary, because if this is solved according to PEMDAS (the order of operations), the multiplication will occur first anyway.
