|
Use appropriate notations [a/b, a to b, a:b] to represent a proportional relationship between quantities and use ratio
language to describe the relationship between quantities. |
Arizona Academic Standards:
6.RP.A.1
|
Understand the concept of a ratio as comparing two quantities multiplicatively or joining/composing the two quantities in a way that preserves a multiplicative relationship. Use ratio language to describe a ratio relationship between two quantities. For example, "There were 2/3 as many men as women at the concert.” |
Common Core State Standards:
Math.6.RP.1 or 6.RP.A.1
|
Understand the concept of a ratio and use ratio language to describe
a ratio relationship between two quantities. For example, “The ratio
of wings to beaks in the bird house at the zoo was 2:1, because for
every 2 wings there was 1 beak.” “For every vote candidate A received,
candidate C received nearly three votes.” |

|
Understand the concept of a ratio including the distinctions between part:part and part:whole and the value of a ratio; part/part and part/whole. Use ratio language to describe a ratio relationship between two quantities. For example: The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every two wings there was one beak; For every vote candidate A received, candidate C received nearly three votes, meaning that candidate C received three out of every four votes or 3/4 of all votes. |
