Step-by-step explanation:
(i) x / 4 = 6/8
Rightarrow x * 8 = 4 * 6 Rightarrow x = (4 * 6)/8 = 3
(ii) 14 / x = 7/9
Rightarrow x * 7 = 14 * 9
Rightarrow x = (14 * 9)/7 = 18
(iii) 4/6 = x / 18
Rightarrow 6x = 4 * 18
Rightarrow x = (4 * 18)/6 = 12
(iv) 8/10 = x / 25
Rightarrow 10x = 25 * 8
Rightarrow x = (25 * 8)/10 = 20
(v) 5/15 = 4 / x
Rightarrow 5x = 15 * 4
Rightarrow x = (15 * 4)/5 = 12
(vi) 16/24 = 6 / x
⇒ 16x = 24 * 6
x = (24 * 6)/16 = 9
