1Objective: Learn to use a table to find equivalent ratios and rates. Using Tables to find equivalent Ratios and rates and create proportionsObjective:Learn to use a table to find equivalent ratios and rates.
2TO create a table of equivalent ratios or rates… Use the same method you used to create equivalent ratios.Multiply or divide the numerator and denominator of a known ratio or rate by the same number.Now we create a table…We used the table to find 5 equivalent ratios. The equivalent ratios are:3= = = = 1536912154
3Your example: Complete the table to create five ratios equivalent to 4 9.Write the 5 equivalent ratios.48121620249
4Creating ProportionsA proportion is a statement that shows two ratios are equal, or proportional.Proportions can be written in word or numbers.For example: 1 = or “One is to two as three is to six.”Complete the table, use the ratios to create three proportions with 2525
5Homework:Use multiplication to complete the table to find five equivalent ratios.2. Complete the table to find 5 equivalent ratios.In 3-5, make a table and create 3 equal ratios. Use the ratios to write 3 proportions.9201121510152025308714212835429
