Final answer:
Omar works 2.5 hours per week, and for a 2-week period, he works a total of 5 hours. To find this, we simplify his daily work hours from 2/4 to 1/2 hour and then calculate the weekly and bi-weekly totals.
Step-by-step explanation:
Omar works 2/4 hours per day, 5 days a week. To calculate the number of hours he works in a 2-week period, let's first simplify 2/4 hours to 1/2 hour because 2/4 can be reduced by dividing both numerator and denominator by 2. Then, we multiply 1/2 hour by 5 days to find the hours worked in a week:
- 1/2 hour/day × 5 days/week = 5/2 hours/week or 2.5 hours/week.
Next, we multiply the weekly hours by 2 to find the total hours worked in a two-week period:
- 2.5 hours/week × 2 weeks = 5 hours total.
Therefore, the correct answer is 5 hours (Option A).
