According to the chart, the youngest age group (ages 13 to 18) watches about
25 hours of entertainment programming per week.
The next age group (ages 19 to 24) watches about
5 hours of entertainment programming per week.
The age group (ages 25 to 30) watches about
10 hours of entertainment programming per week.
We want to find: (
average number of hours per week the youngest age group spent watching entertainment on TV)/(
average number of hours the other two groups combined spent watching entertainment on TV)
We get:
25/(
5 +
10) =
25/15 =
5/3 =
