### Diana's Proportion Post

Part 1:

Rate- Compares two quantities measured in different units.

Eg. \$1.69 per 100g or \$1.69/100g is a rate for purchasing bulk food.

Ratio- A comparison of 2 quantities that both have the same unit of measure.

Proportion- An equation which states that two ratios are equal.

Part 2:
1) 5 hours to travel 360 kilometers is about __72__ km/h

2) Emma saves 28 cents of every dollar that she earns. Emma earned 75\$ last week.  How much money did Emma save last week?

Part 3:
What are the three ways you can prove that equivalent ratio statements are true?
3/4= 12/16 or.. 4/9=16/32

2) Dividing.
3) Multiplying.

Part 4:

Part 5:

1) Not fair.
2) Nope
3) Because Roy only took a 100\$ bill, he gave it back anyways. He was hungry and homeless. He felt bad, because he said his mother didn't raise him that way, so he returned the money. Paul stole 3 billion dollars and got a 4 month sentence. Roy got a 15 year sentence, it's not fair at all.
4) I would've gave him like 24 hours of community service. It was just 100\$, not a lot compared to what Paul took. Plus he was homeless and hungry.
