Question

round to the nearest whole number 581.632

Answer 1

Locate the units digit. This is the red digit shown below

\[\large 58{\color{red}1}.632\]


The next digit is a 6, which is greater than 5. So add 1 to the red units digit to get 1+1=2. This is the new units digit. Finally, drop everything after the red one to complete the rounding. So \[\large 58{\color{red}1}.632\] becomes \[\large 58{\color{red}2}\]

Answer 2

In short, rounding 581.632 to the nearest whole number results in 582.
