7.897 rounded to the nearest whole number

7.897 is about 8 (rounded to the next whole number)

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 :)
