if the ratio is 7647 / 54782 and 7647 represents the number of 65+  yr old residents in the northeast (to the thousandths) and 54782 represents the whole northeast region, then this means there are ??? people from ages 65+ for every 1000 people in the northeast region.

I would approach this question by setting up a proportion with "x" as what we're trying to find.

7647/54782 = x/1000

Now cross multiply (numerator of the left side times the denominator of the right side and vice versa)

7647*1000 = 54782x

Divide by 54782 to solve for x.

There are approximately 140 people who are ages 65+ for every 1000 people in the Northeast.

Thank you! I appreciate your help.  That is what i came up with as well but when i put it in... It says it's wrong.  We have to go out to the thousandths place so i put 139.589.  Any suggestions?

Maybe try putting 140 then?
