1. Objective: Learn to use a table to find equivalent ratios and rates.
Using Tables to find equivalent Ratios and rates and create proportions
Objective:
Learn to use a table to find equivalent ratios and rates.

2. TO 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= = = = 15 3 6 9 12 15 4

3. Your example: Complete the table to create five ratios equivalent to 49.
Write the 5 equivalent ratios. 4 8 12 16 20 24 9

4. Creating Proportions
A 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 2 5 2 5

5. Homework:
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. 9 20 11 21 5 10 15 20 25 30 8 7 14 21 28 35 42 9
