How do you estimate? I don't really understand because for one question my teacher said you wouldn't round your numbers, but for a different problem, he rounded the factors?

You can round up to tenths, hundredths, thousandths, or tens, hundreds, and thousands. Some numbers, they have remainders when divided, so you would round them up to make them whole numbers or non-repeating decimals.

Hope this helps!!

Let me know if you need more information...
