The population density of Montana is 6.699 people per square mile. What is the population density per square mile of Montana rounded to the nearest whole number?

##7## people per square mile

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.
