Question

7.897 rounded to the nearest whole number

Answer 1

Rounded to the nearest whole number in this case means that you are going to use the number that is in the tenths place and see if it rounds the 7 up.

7                                  .                   8               9                  7                      
^      
whole number - decimal point - tenths - hundreths - thousandths

using a and b

*if the question is asking you to round a to the the nearest whole number then you have to look at b  and see if it is 5 or more. if it is then it rounds a up. if b is 4 or less then a  either is rounded down or stays the same.
------------------------------------------------------------------------------------------------------
 in this case

the 8 after the decimal point rounds the 7 up so your final answer is going to be:

8

hope this helps :)
