in 2050 about (1)/(5) of the population will be aged 65 or over and about (1)/(20) of the population will be aged 85 or over. estimate the fraction of the population that wll be between he ages of 65 and 85 in 2050


I need help on how to solve this problem, i dont know where to start or finish.

"Over age 85" is included in "over age 65"

\(\displaystyle \frac{1}{5} - \frac{1}{20}\)

This is the amount between 65 and 85.
