What were the Silk Roads, and why were they important?

The Silk Road was a network of trade routes connecting China and the Far East with the Middle East and Europe.

The Silk Road was important because it helped to generate trade and commerce between a number of different kingdoms and empires. This helped for ideas, culture, inventions, and unique products to spread across much of the settled world.

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".
