 Description: A unit that defines the word percent and explains the meaning of the percent symbol, and shows the relation between percentages and their equivalent fractions and decimals, giving a method for converting one form to the others. Four general types of problems are discussed: 1) finding a percent of a given number, 2) finding what percent one number is of another, 3) finding a number when a percent of it is given, 4) finding what percent greater or smaller one number is than another. The unit then applies the skills to consumer-related problems: sales tax and gratuities, discount, commission, simple interest, and compound interest. Sample problems with detailed solutions are illustrated, and problems to be solved by students are included.
