3 $52.65 5.4 hrs $9.75
The Employee 2 earned the least per hour.
Explanation:
Consider the provided table:
The table shows the earnings and the numbers of hours worked three employees.
Employee 1)
Employees 1: Total earn $34.02 and earning per hours is $9.72
We need to find the number of hours worked.
To find this divide the total earning by earning per hours as shown:

Hence, Employee 1 work for 3.5 hours
Employee 2)
Employee 2: Total earn $42.75 and work for 4.5 hours
We need to find the earning per hours.
To find this divide the total earning by number of hours worked as shown:

Hence, Employee 2 earning per hours is $9.5.
Employee 3)
Employee 3: Total earn $52.65 and earning per hours is $9.75
We need to find the number of hours worked.
To find this divide the total earning by earning per hours as shown:

Hence, Employee 3 work for 5.4 hours
The complete table is:
Employees Total earn no. of hrs worked earning per hrs
1 $34.02 3.5 hrs $9.72
2 $42.75 4.5 hrs $9.50
3 $52.65 5.4 hrs $9.75
Now we need to find which employees earned the least per hour.
Employee 1 gets $9.72 per hours
Employee 2 gets $9.50 per hours
Employee 3 gets $9.75 per hours
Here, it is clear that $9.50 is the least amount among them. So the Employee 2 earned the least per hour.
