Comparing Ratios

Comparing Ratios

Make sure you have a pencil and paper,

and pull up the math lesson in a tab.

I can...

• Determine equivalent ratios.

• Compare ratios.

  Determine the missing values in a table of equivalent ratios.

• Plot values of a ratio on a coordinate plane.

• Solve math and word problems using ratios.

Standards

• 6.AF.9

  Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane.

• 6.NS.10

  Use reasoning involving rates and ratios to model real-world and other mathematical problems (e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations).

Lemonade ratio

• The ratio of lemon juice to water for lemonade is 1:5 (+ :1 sugar)

Multiple Select

If the ratio of lemon juice to water is 1 Cup of lemon juice to 5 cups of water, which of these options describe the ratio of lemon juice to water correctly

• 1:5

• 2:15

• 3:15

• 5:25

Comparing Ratios

Ratios are useful for making comparisons. For example, in one karate class, the student-to-teacher ratio may be   $\frac{8}{1}$  , which means that there are 8 students for every 1 teacher. In another class, the ratio may be  $\frac{12}{1}$  , which means that are there are 12 students for every 1 teacher. The ratio  $\frac{12}{1}$  is greater than $\frac{8}{1}$   , so the second karate class has a greater student-to-teacher ratio.
