What is the importance of the sit-ins and the freedom rides?

How important were the Freedom Rides? The Freedom Rides, like the sit-ins before them, demonstrated that anyone who opposed segregation could take action themselves to work towards ending Jim Crow Laws. They helped the spread of civil rights in the south. I really hope this helps you :)

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".
