Ratios & Proportional Relationships


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."


What are the rest of the lyrics?

Using the phrase “For every...” is essential when learning ratios. During For Every Day, Delta Team Geologist Kim O’Hara is on Mars at the home base, and she is rationing her food supply until her team returns from their supply mission. Aside from determining how much of each item she can have per day, she decides to write a rap song, “For Every Day” to help her remember the quantities so she doesn’t overeat. The data provided is O’Hara’s notes: a reminder that she has to ration for 80 days, her food inventory, and the first two lyrics of the song which begin with the phrase: “For Every Day.”
