Step-by-step explanation:
(i) 6 : 8 and 12 : 16
6 : 8 = 6/8 = 3/4
12 : 16 = 12/16 = 3/4
Thus, the ratios 6 : 8 and 12 : 16 are equal.
Therefore, they form a proportion.
(ii) 24 : 28 and 36 : 48
24 : 28 = 24/28 = 6/7
36 : 48 = 36/48 = 3/4
Thus, the ratios 24 : 28 and 36 : 48 are unequal.
Therefore, they do not form a proportion.
