Final answer:
To express the part-to-part ratio of the hours doing homework compared with the hours watching TV or playing video games as a percentage. Hence, none of the options are correct.
Step-by-step explanation:
To express the part-to-part ratio of the hours doing homework compared with the hours watching TV or playing video games as a percentage, we need to determine the proportion of time spent on each activity.
Let's assume that the number of hours doing homework is 5 and the number of hours watching TV or playing video games is 10. The part-to-part ratio is calculated by dividing the hours doing homework by the total hours of both activities: 5 / (5 + 10) = 5 / 15 = 1/3.
To express this ratio as a percentage, we multiply it by 100: (1/3) * 100 = 33.33%. Therefore, the correct answer is not provided in the options given. The part-to-part ratio of the hours doing homework compared with the hours watching TV or playing video games is approximately 33.33%.
