Expert Answer:
Here, 
(i) Let u = 6 and v = 8
Therefore, 
Since the ratio is same as in (a), so it is the corresponding value of u and v.
(ii) Let u = 15 and v = 20
Therefore, 
Since the ratio is same as in (a), so it is the corresponding value of u and v.
(ii) Let u = 18 and v = 22
Therefore, 
Since the ratio is not same as in (a), so it is not the corresponding value of u and v.
