| Ques. Determine the ratio: (i) 5 km to 400 m (ii) 2 hours to 160 minutes Ans. (i) 5 km = 5 × 1000 = 5000 m Therefore, The ratio of 5 km to 400 m = 5000 m : 400 m = 25 : 2 Thus, the required ratio = 25:2 (ii) 2 hours = 2 × 60 = 120 minutes Therefore, the ratio of 2 hours to 160 minutes = 120 : 160 = 3 : 4 Thus, the required ratio = 3:4 |
