You are the manager of an assembly plant and have determined that the employee of the week would be the one that was the most efficient. jimmy worked a total of 30 hours and assembled a total of 80 radios, jordan worked a total of 42 hours and assembled a total of 115 radios and denise worked a total of 38 hours and assembled a total of 100 radios. to determine the employee of the week you divided the number of radios assembled by the number of hours worked and rewarded the employee that got the highest number. is this the correct method?

Yes, this is a good method.

Step-by-step explanation:

Since the ratio of the number of radios assembled to the number of hours worked shows the work efficiency of an employee.

Also, the employee who works less hours and assembled more radios are more efficient, that employee knows how to utilize time.

So, Giving the reward to the employee whose ratio is the highest number is the correct method to judge the efficient.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
