Task 2
1) 5 hours to travel 360 miles in about 72 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.
Task 3
What are the three ways you can prove that equivalent ratio statements are true?
3/4 = 12/16
You can multiply the top left to the bottom right. You can also diagonally, horizontally, and vertically
Task 4
Task 5
1) Does this seem fair?
Not at all
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?
It is not fair because the guy had a $3B fraud and the judge let him go to jail for only 3 years while the other guy robbed $100 from the bank and gave it back and the judge gave him 15 years in jail.
3) What would you have done if you were the judge?
If I was the judge I would charge the guy that took $3B 15 years to jail and the homeless guy that stole $100 and returned it to 3 years of jail
