15. Wednesday, Sept 2 Lesson 1.4 Ratio Tables

16. Objective: To use ratio tables to represent and solve problems involving equivalent ratios.

17. Ratio Tables Equivalent ratios express the same relationship between quantities. 1: 2 is equivalent to 2: 4 is equivalent to 4: 8 is equivalent to 8:16 is equivalent to 16:32 is equivalent to ?

18. Ratio Tables

20. A ratio table is a table which contains equivalent ratios.
