- Does this seem fair?
- 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?
- What would you have done if you were the judge?

1 a) No this doesnt seem fair.

2 a) No!!!

3 a) Because the buissness man stole 3 billion dollars and was only sent to jail for 40 months!!! The homeless man only stole 100 dollars and he gets 15 years. Plus the homeless man gave it back he felt guilty!!!

4a) Sure the homeless man did steal but he gave back the money he stole. He should have only got 5 months . I feel bad for the homeless man, but he did steal. The man that stole 3 billion should have been the one to get 15 years!

If the box was 47 cm tall, how tall would the "British Columbia" sign be?

The box is 4.7 cm tall on my screen and the sign is 3.5cm tall. So 4.7cmx10= 47cm, 3.5cmx10=35. So if the box was 47 cm tall the sign would be 35cm.

3 stars: One the British columbia question math and the way I explained it. Part 3 how I took the time to do it on paper.My ratio definition.
