Reiner's Proportion Post

Part 1

Rate : compares 2 quantities of different units

Ratios : comparison of one number to other numbers
Proportions : 2 equivalent fractions, ratio, rates

Part 2:

1. 5 hours to travel 360 kilometers is about 1.25 km/h

2. She saved 0.74 cents for every hours of everyday last week

Part 3:

3/4 + 12/16 because 3 X 4+ 12 and 4 X 4 = 6 while 4/9 = 16/32 is not.

Part 4:

Part 5:

1. No
2. No
3. Because the man who stole 3$ billion dollars is only sentenced to jail for 6 years while the homeless man who only stole 100$ was sentenced to jail for 15 years. At least the man will no longer be homeless and hungry, he has a bed to sleep on and the prison will give him food everyday so he won't starve.
4. If I was a judge, I would've only sentenced the homeless man 5 years in jail while the guy who stole the 3$ billion dollars, I would've sentenced him to a lifetime in prison.
