Answer: Z=
(x)/(50) =
(40)/(100)

Step-by-step explanation: Okay, so look at the attachment for a better understanding. Now, you cross multiply the 50 and the 40, to get 2000. Then, you divide 2000 by 100 to get 20. So, it should look like z= (40 x 50) / 100. Therefore, if you would want an answer, it would be 20. But, "Z=
(x)/(50) =
(40)/(100)" is your relationship. I hope this helped!
