PPT-Representing Ratios

Part 1 Concrete Models Tape Diagrams Refresher Remember we learned last week that a RATIO is the RELATIONSHIP BETWEEN TWO QUANTITIES There are 3 types of ratios Part to Part Part to Whole. Ratios ratios are one number expressed in relation to another by dividing the one number by the other For example the sex ratio of Delaware in 1990 was 343200 females to 322968 males or 106 This can easily be expressed in terms of males to females 9 Representing Relations Using Matrices.
