Oudorn's Proportion Post

Ratio: A ratio is a comparison of two quantities that have the same unit of measure.
Rate: A rate is a comparison of two quantities measured in different units.
Proportion: A equation which states that two ratios or fractions are equal.

1. 5 hours to travel 360 miles is about 76 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.

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.

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 dont think its fair because the rich guy is going to jail for 3 years because he stole 3billion and the homeless is going to jail for 15 years just for stealing 100 dollars.

3.What would you have done if you were the judge?

I would make the rich guy go to jail for 15 years and the homeless guy go to jail for 3 years.
