Two-term ratio: compares two quantities measured in the same unit.
Three-term ratio: compares three quantities measured in the same unit.
Part-to-Part ratio: compares different parts of a group to each other.
Part-to-whole ratio: compares one part of a group to the whole group.
Rate: Is a ratio that compares two things. Ex. miles per hour, the cost per pound
Proportion: Is an equation which states that two ratios or fractions that are equal. Ex. 3/4 = 6/8
1.) 5 hours to travel 360 miles is about _____mph
2.)As a playgroup worker, if I increase the amount of apple juice I am serving at the playgroup from 25 ml to 100 ml, how much should I increase the the orange juice to, to keep the quantities in the same proportion? The orange juice is 50 ml to start with.
3.What are the three ways you can prove that equivalent ratio statements are true?3/4 = 12/16 or 4/9 = 16/32
1.Does this seem fair?
No, it does not seem fair.
2.With what you know about proportion look and read what is in the image above. Does it seem just and fair? Why have you made this choice?
I said it's not fair because the homeless man was in jail for 15 years for taking 100 dollars. The rich guy who took 3 billion dollars, which is 30 millions times more than what the homeless man took, only had to be in jail for 40 months.
3.What would you have done if you were the judge?
If I were the judge, I would try to give the homeless man less years in jail because he had went to the police and told them whet he did. I would also try to give the CEO more years in jail, because he is a highly educated adult who should know what he should do and what he should't. He needed more years in jail to learn how to be a good citizen.
