Answer 10

14.7 is the answer. To estimate you have to round. Is 14.7 closest to 15 or 14?

Answer 11

because he knows what i am talking about

2.45 is NEAR 2.5
6.8 is NEAR 7

You could estimate the answer as 2.5 x 7

You could even estimate it as 2 x 7 or as 3 x 7

yeppers.

Answer 20

That's not how they teach them to estimate answers... you don't solve first then round, you round first then multiply.

It's less precise, but it is a tool for getting a general order of magnitude answer...

Ex) "about how much will our restaurant dinner cost?" Estimate each meal price quickly, multiply by number of people... etc.

Answer 21

Oh...that could be it.

Answer 22

Guys! To make an estimate, you don't calculate the exact answer and then round it. Er, what you do is round the parts you're dealing with and get a rough answer. So 2.5 x 7 was good. How about 17.5 or round that a bit?

Answer 23

you can round 2.45 down to 2
round 6.8 up to 7

Multiply 2 x 7 to get 14.

Yes, it's several off from the true answer, but it is an estimate...

Answer 24

Okay, okay. Sorry @FLUFFYKITTY if we are confusing you.

Answer 25

2.5 x 7 is really good, but the answer isn't one of the ones @FLUFFYKITTY has to choose from.

Answer 26

JakeV8 is right.

Answer 27

It's that I don't "estimate" answers anymore. I am in eighth grade, and I do more complicated things.

Answer 28

So, from the given options, it has to be 14. Round one of your starting numbers up, the other down and Bob's your uncle. (Sorry -- I missed the specific answer choices the first time.)

Answer 29

(The option of 15, by the way, although closest to the correct answer, is a red herring. If you're using any sensible estimating method, you don't come up with 15, even though it's closer.)

Answer 30

Good points @Biffo
