Number of people who were under 18 years old and living in the United States in 1970 = 70 million

70*80/100=56 million

The number of people 50 years old or older living in the United States in 2020=120 million

56/120=7/15

Re: According to the graph above, if 80 percent who were under 18 years ol [#permalink]
I used the Empower method to narrow down the answer choices. After I figured out the answer was 56/120 , I realized this is slightly less than half (can also be written as 5.6/12) Half would be 6/12. All of the answer choices except E are very obviously larger than half. E is the only one that "fits"
