For example : the ratio for red circles to clue is 4:6 .
what's proportion?
A proportion is like a part in relation to the whole.
for example :

What are the three ways you can prove that equivalent ratio statements are true?
·  Does this seem fair?  No this doesn't seem fair , because he didnt take all the money and he surrendered.
·  With what you know about proportion look and read what is in the image above.  Does it seem just and fair?  yes.
·  Why have you made this choice? Because it seems fair and he dserves a second chance.
·  What would you have done if you were the judge? I would of gave him a warning & thanks him for giving the money back.
