Using Tables to find equivalent Ratios and ratesand create proportions

Objective:

Learn to use a table to find equivalent ratios and 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= 6 = 9 = 12 = 15

4 8 12 16 20

- Complete the table to create five ratios equivalent to 4
9.

Write the 5 equivalent ratios.

- A proportion is a statement that shows two ratios are equal, or proportional.
- Proportions can be written in word or numbers.
For example: 1 = 3 or “One is to two as three is to six.”

- Complete the table, use the ratios to create three proportions with 2
5

In 3-5, make a table and create 3 equal ratios. Use the ratios to write 3 proportions.
