1. The model height of No.1 building in Huayuan district is 0.35m, and its actual height to model height ratio is 500:1. How many meters is the actual height of No.1 building? 2. One fifth of number a is equal to one fourth of number B. find the ratio of number a to number B 3. The museum displays a 19.6cm high model of the Qin Dynasty general figurine. The ratio of its height to the actual height is 1:10. What is the actual height of the general Figurine? 4. The actual height of No.1 building in Yuxin community is 35m, and its height to model height ratio is 500:1?

The actual height of No.1 building in Yuxin community is 35m, and its height to model height ratio is 500:1?

1. Let the actual height be x, where 500:1 = x: 0.35, x = 500 * 0.35 = 175m
2. Let a ratio B be: X: y, then (1 / 5) x = (1 / 4) y, X: y = 5:4
3. Suppose that the actual height of the general figurine is x, then 19.6: x = 1:10, then x = 196
4. Suppose the height of the model is x, and the actual height is 35m, that is 3500cm, then 3500: x = 500: 1, then x = 7cm
