#7# people per square mile

Explanation:

Rounding #6.699# to the nearest whole number means that there should be no decimals. Thus, start by looking at the number before the decimal, #6#.

#rArrcolor(red)(6).699#

Then look at the number after it, #6#.

#rArr6.##color(red)(6)99#

Since the #6# after the decimal is greater than #5#, that means you must raise the value of the decimal-preceding #6# by #1# and not write any numbers after it since you are rounding to the nearest whole number .

#rArr(6+1)color(red)cancelcolor(black)(.699)#

#rArrcolor(green)(|bar(ul(color(white)(a/a)7color(white)(a/a)|)))#

#:.#, the population density of Montana is #7# people per square mile.
