Diana's Proportion Post

Task 1: Definitions:
two-term ratio: compares two quantities measured in the same units
three-term ratio: compares three quantities measured in the same units.
part-to-part ratio: compares
different parts of a group to each other.
part-to-whole ratio: compares one part of a group to the whole group.

a comparisson of two auntities measured in different units.
EX. $1.69 per grams or $1.69/1
00g that is a rate for purchasing at bulk barn.

Proportion- an equation which states that two fractions are equal.h

Task 2:
Question 1) 5 hours to travel 360 miles is about 72 mph.

Question 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 or 4/9 = 16/32
Answer: you can multiply the top left to the bottom right. also you can do it diagonally, horizontally, and vertically

Task 4: Heres a video about proportions

Task 5:
1)Does this seem fair?No, this is not 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? It's not fair because. The man who stole $ 3 billion and was only sentenced for 40 months in jail . And the homeless man who stole $100 who surrendered himself and gave back the money was sentenced for 15 years in jail.
3) What would you have done if you were the judge? If I were the judge, I would sentence the man who stole $3 billion 15 years in jail instead of the homeless man because the homeless man brought himself in and gave back the money.
