Description
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.
Explanation & Answer
Thank you for the opportunity to help you with your question!
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.
Final answer: x = 139.59
There are approximately 140 people who are ages 65+ for every 1000 people in the Northeast.
