Rate: A rate is a comparison of two quantities measured in different units. e.g. 2 hotdogs/$ 3.00
Proportion: A proportion is an equation which states that 2 ratios are equal.

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?

1. Does this seem fair? No, this is not fair. The homeless man turned himself in after stealing the $100. Only 100 and he turned himself in. But he gets sent to 15 years in prison. on the other hand, a wealthy man tries to steal 3 BILLION dollars. He gets caught and gets sent ONLY to three years in prison.

3. If i were the judge, I would have just sentenced the homeless man to do community service or even just give him a warning. As for the other man, i would have sentenced him to 20 years in prison.
