Real-Life Math -- Solution

If 50,500 people lived in your city in 1980 and 1 out of every 20 was over 65, then you would divide to find the actual number.

50,500 / 20 = 2,525

In 1980, 2,525 people were 65 or older.

Twenty years later, there were 10,100 people 65 or older. By what factor did this elderly population increase?

Again, we can divide to get the answer.

10,100 / 2,525 = 4

The elderly population increased by a factor of 4.
