Answer: Daniel worked the most hours
Step-by-step explanation: To determine who volunteered the most hours, we need to compare the hours volunteered by Casey, Danielle, Javier, and Forrest.
First, let's convert all the hours to a common fraction or decimal format for easier comparison:
- Casey volunteered 20.7 hours.
- Danielle volunteered 20 3/4 hours, which is equivalent to 20.75 hours.
- Javier volunteered 18 9/10 hours, which is equivalent to 18.9 hours.
- Forrest volunteered 20 18/25 hours, which is equivalent to 20.72 hours.
Now, we can see that Danielle volunteered the greatest number of hours, with 20.75 hours.
In summary, Danielle volunteered the most significant number of hours among the four students.
