Final answer:
Two ratio tables are created to compare current and proposed commercial to show time on television. The current ratio is 13:47 and the proposed ratio is 3:7, resulting in an increase in commercial time and a slight decrease in show time.
Step-by-step explanation:
The question pertains to creating two ratio tables for comparing normal commercial programming time and proposed commercial programming time for a television show. Currently, most television shows use a 13:47 ratio of commercials to actual show time - this means for every 60 minutes, 13 minutes are allotted to commercials and the remaining 47 minutes to the actual programming content.
The proposed ratio is 3:7 for commercials to show, respectively. To create the ratio tables, let's consider an hour of programming (60 minutes) for both current and proposed ratios. For the standard ratio, we find that commercials take up 13 minutes and shows take up 47 minutes. This is simplified as:
- Commercials: 13 minutes
- Show: 47 minutes
For the proposed ratio of 3:7 within the same hour, we have a total of 10 parts because 3+7 equals 10. Each part now represents 60 minutes ÷ 10 parts = 6 minutes per part. Multiplying by the ratio gives us:
- Commercials: 3 parts × 6 minutes/part = 18 minutes
- Show: 7 parts × 6 minutes/part = 42 minutes
The ratio tables help visualize how the time dedicated to commercials and programming content would change with the proposed new ratio, resulting in more commercial time and slightly less show time than the current standard.
