Melvin's Proportion post

ratio: It compares different parts of a whole, it is similar to a fractions
rate: Compares two quantities measured in different units.
proportion: A proportion makes a equivalent fraction in the same units they where already in.

Ratio ex: 1:4 blue balls to red balls, this means for every blue ball there are 4 red balls.
Rate Ex:$/H this means if a how much a worker earns per hour.
Proportion Ex: Km/H this means how many km a car can travel in one hour.

1. 5 hours to travel 360 kilometers is about _____km/h.
2. 5H/360km= ?/720 5x720= 3600 divided by 360= 10 10 hours to travel 720km. 10 divided by 10 =1 and 720 divided by 10 = 72km 72km/H
3. Emma saves 28 cents of every dollar that she earns.  Emma earned $75 last week.  How much money did Emma save last week?
   75 divided by 0.28x75= 21 dollars

What are the three ways you can prove that equivalent ratio statements are true?
3/4 = 12/16  is false because 3x4= 12 but 4x3=12 not 16 which proves its not equivalent.

Part 4

1. It doesn't look fair but I think the judge was just being nice to the homeless guy.

1. it isn't fair because the other guy was going to steal much more than the homeless guy and the homeless guy gave it back.
    
2. so the homeless guy gets food in jail and shelter
3. I would do the same so the homeless guy can survive in jail.
