Question

How to round or estimate

Answer 1

To round is like = 6,500, which would round to 7,000 if you were rounding the 6 in 6,500. But if the number to the right of the number you are rounding is less than 5 then the number stays the same and the numbers to the right are turned into 0. I.E. 6,500 rounds to 7,000 but if it is 6,400 it rounds down and goes to 6,000.


But to estimate is to find an awnser by using rounding or something similar to find an answer close to the Awnser wanted.

Answer 2

Find the place value you want (the "rounding digit") and look to the digit just to the right of it.If that digit is less than 5, do not change the "rounding digit" but change all digits to the right of the "rounding digit" to zero. hope this helps
