Final answer:
The ratio of pencils to erasers in three different ways is 7:2, 7/2, or 7 pencils to 2 erasers.
Step-by-step explanation:
The question is asking for three different ratios of pencils to erasers. To find the ratio, we need to compare the number of pencils to the number of erasers. Based on the contents of Dean's pencil box, we can see that there are 7 pencils and 2 erasers. Here are three different ways to express the ratio:
- 7 pencils to 2 erasers
- 7:2
- 7/2
These ratios indicate that for every 7 pencils, there are 2 erasers.
