TASK 1 :Ratios :
Two-term-ratio - compares two quantities measured in the same units .
Written has a:b or a to b .
Three-term ratio - compares quantities measured in the same units .Written as a:b:c or a to b to c .
Part-to-part ratio - compares different of a group to each other.
10:8 is a part-to-part ratio of 10 black beans and 8 red beads.
Part-to-whole ratio - compares one part of the group to the whole group.
5:23 is a part-to-whole ratio of blue beads to
Rate - A comparison of two quantities measured in different units.
EX: $1.69per grams or $1.69/100g that is a rate for purchasing food at bulk barn.
Unit rate - A rate which the second term is one.
EX: 64 beats/min (minute is a unit rate.)
Proportion -The relationship of two variables whose ratio is constant.
TASK 2 :
1. 5 hours to travel 360 miles is 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 multiply diagonally from top left and bottom right and vertically, and horizontally
TASK 4 .:
Here is a video to help you with proportions . I don't know how to get the video on here , so here is a link
http://www.youtube.com/watch?v=VikfwNpnZ10 Enjoy !
1. Does this seem fair ?
No it doesn't seem fair 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?
I don't think this is fair at all. I'm thinking this because the rich man stole $ 3 Billion dollars and only got 40 months in jail and a poor , hungry man stole only $ 100 dollars and got 15 years in jail , but he returned the money back afterwards because he felt bad.
3. What would you have done if you were the judge.
What I would have done if I was the judge is asked the rich man to pay the money back and sentence him for 2 years( because he would pay the money.) I would give the poor man 2 months in jail.
I hope this helped anyone that was having trouble
