Best ResponseYou've already chosen the best response.0use the calculator to do this. Or there is not permited to use it? your answer is not correct if the sing between the ( ) is multiplication

Best ResponseYou've already chosen the best response.2okay, if we round to the nearest whole unit, what are the rounded off values of 4.18, 1.93 and 8.72?

Best ResponseYou've already chosen the best response.2"nearest whole unit" means "nearest counting number"

Best ResponseYou've already chosen the best response.2very good. if we use my method from previous problem, we are rounding to the 1's place, so we add 0.5 4.18 +0.5  4.68 drop everything after the place where we are rounding 4 our first number is (4) how about the next two?

Best ResponseYou've already chosen the best response.2Okay, so we had "simplified" our expression from \[(4.18)(1.93)(8.72)\] to \[(4)(1.93)(8.72)\] but we still need to round the second two numbers before multiplying to get our estimate

Best ResponseYou've already chosen the best response.2what is the nearest counting number to 1.93?

Best ResponseYou've already chosen the best response.2as an old math teacher of mine used to say when someone answered without conviction in their voice, "is that an answer, or a prayer?" :)

Best ResponseYou've already chosen the best response.2that's better! How about the third one?

Best ResponseYou've already chosen the best response.2correctamundo. so now we have which 3 numbers to multiply together?

Best ResponseYou've already chosen the best response.2excellent! if we'd done the problem as originally stated, we would have 70.347728 so our estimate is pretty good, and a lot less work!

Best ResponseYou've already chosen the best response.0So it would be 70.347728 or do with take off some numbers?

Best ResponseYou've already chosen the best response.2No, the answer is 72. I'm just telling you what we would have gotten if we hadn't done an estimate, but instead multiplied the 3 original numbers in all of their magnificence :)
