Task 1:

What is a ratio? A ratio is the relation between two similar magnitudes with respect to the number of times the first contains the second: the ratio of 5 to 2, written as 5:2 or 5/2.

What is a rate? A rate is a comparison of two quantities measured in different units. $1.69 per 100 grams or $1.69/100g is a rate for purchasing bulk food. 72 beats per min is a heart rate.

What is a proportion? A porportion is an equation which states that two ratios (fractions) are equal.

Task 2:

1) 5 hours to travel 360 miles is about _____ 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 orange juice to, to keep the quantities in the same proportion? The orange juice is 50 ml to start with.

If you increase the amount of apple juice yoiu are serving to 100 ml, then you would have to serve 200 mlof orange juice to the playgroup kids.

Task 3: What are the three ways you can prove

that equivalent ratio statements are true?

Task 4:

Task 5:

1) Does this seem fair? Yes it is fair.

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? I think its fair because this homeless man did something he shouldn't have done. If he was really poor, he can go to a shelter or one of those places where homeless people get free food. I think 15 years of jail is good for him.

3) If I was the judge, I would of probably have kept it to 15 years.
