Best ResponseYou've already chosen the best response.0that would be incorrect, because 686.13 ÷ 9.231=74.3288918 and since the second number is four, when you round down you get 70

Best ResponseYou've already chosen the best response.2Horrible. Absolutely horrible. What's the point of estimation if you're just using a calculator?! 686.13 isn't too far from 700 9.231 isn't too far from 10 700 / 10 = 70  Now THAT is an estimate.

Best ResponseYou've already chosen the best response.2"Your way" isn't a way at all. It's just using a calculator. That will not EVER be a good way to produce a quick and useful estimate in your head. It's just using a calculator. That will not help you when the grid goes down, you run out of fuel in your generator, and your last battery dies. The problem is to teach estimating. Calculator usage is a different class.
