8. A personal trainer's workout recommendations are: 1/3 focus on cardiovascular fitness, 1/2 focus on strength training, remaining focus on stretching. According to this recommendation, approximately what percent of a person's workouts should focus on stretching? (Round your answer to the nearest whole percent.)
Answer: B
Approximately 17% of a person's workouts should focus on stretching.
Given the workout recommendations, if 1/3 is devoted to cardiovascular fitness and 1/2 to strength training, the remaining portion for stretching is calculated as follows: 1 - (1/3 + 1/2) = 1 - (2/6 + 3/6) = 1 - 5/6 = 1/6, which is approximately 17%.
A) 83%
This option is incorrect as it represents a larger proportion than what is allocated for stretching. Based on the given recommendations, stretching comprises only a fraction of the total workout time.
B) 17.00%
This option is correct as it reflects the accurate calculation of the remaining workout focus. After determining the portions for cardiovascular fitness and strength training, the stretching component is confirmed to be approximately 17%.
C) 80%
This option is incorrect because it suggests an excessively high percentage for stretching. The calculations indicate that stretching only makes up a minor fraction of the workout, not the majority.
D) 20%
While this option is relatively close, it is still inaccurate. The correct portion for stretching is approximately 17%, not 20%, based on the outlined recommendations.
Conclusion
The correct answer is 17%, as derived from the calculations of the workout distribution. All other options misrepresent the percentage allocated to stretching, either by overstating or miscalculating the remaining focus after accounting for cardiovascular and strength training components. Thus, option B is the only accurate choice.
