720/8 = 90
280 + 500 = 780
That equals 559. If you have to, estimate 210 + 350 = 560
Not in this case.
It is 0.7*600 = 420
You divide them the same way that you would using 1 or 2 numbers. It is just diving 3 numbers into a number instead of just using 1 or 2. It is that simple. It is just annoying having to manually doit though. I use a calculator now that I am out of school. Good luck.
