A survey of 100 people found that 35 people exercise in the morning, 45 people exercise in the afternoon, and 20 people exercise at night. Tara claims that 35:55, 45:80, and 20:65 are possible ratios from this data. Jim claims that 35:100, 45:100, and 20:100 are possible ratios from this data. Who is correct? Explain.​

100 total people ... 35 exercise in the morning ... 45 in the afternoon ... and 20 at night

Jim is correct ...

35/100 is the ratio of people who exercise in the morning to total people.

45/100 is the ratio of afternoon exercisers to total people

20/100 is the ratio of night exercisers to total people

Answer 2

Answer: Jim is correct because 35:100, 45:100, and 20:100 are part-to-whole comparisons. There are other possible part-to-part ratios from the data.
