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.
