Which of these measures increased significantly during the two decades following the end of world war ii?

a) interest rates
b) birth rate
c) inflation rate
d) union membership rates

i believe its b) birth rate cause of the baby boom

The answer is B birth rate because after World War 2 people could start having more kids now that they could afford it. Before women would not do that because they could barely pay for themselves as it was.

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".
