What happened in china during the warring states period of the zhou dynasty between 476-221 b. c.e.?

The Warring States period was a period in which the regional warlords annexed smaller states around them and consolidated their mandate.

The Warring States period witnessed the proliferation of iron works in China, replacing bronze as the dominant metal used in the war machine. The walls built by the states to keep away the nomadic tribes of the north and the other states were the precursors of the Great Wall of China. Trade also reached great importance, and some merchants reached a considerable power in the politics of government. Military tactics also changed. Unlike the Spring and Autumn period, most of the armies in the Warring States period made a combined use of infantry and cavalry, and the cars gradually fell into disuse.

explanation:

part a. there were 250 teenagers surveyed (100% of tenagers = 250)therefore 1 % = 250/100 = 2.5 76% = 1% x 76 = 2.5 x 76 = 190 teenagers of the 250 surveyed liked burgerspart b: jane surveyed 25% (which is equal to 50 teenagers, i.e. a quarter of the teenagers surveyed is 50) to get 100% we simply get 4 quarters, i.e. multiply 50 by 4 = 200 teenagers were surveyed by jane. part c: it is impossible to give an example where a percentage is greater than 100%, since, by definition , percentage means "per 100".
