Out of the 1500 men who responded to the study, the fraction of men who actively tried to reduce their stress is 7/20.
To determine the fractional part of the men who actively tried to reduce their stress, we need to analyze the given circle graph.
From the graph, we can see that the category "Actively tried to reduce their stress" for men has a value of 525.
To find the fractional part, we need to divide the value of men who actively tried to reduce their stress (525) by the total number of respondents (1500 men).
Therefore, the fractional part of men who actively tried to reduce their stress is 525/1500.
To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 75.
So, 525/1500 simplifies to 7/20.
Therefore, the fractional part of the men who actively tried to reduce their stress is 7/20.
