Aaron S Proportion statement

Aaron's Proportion Post.

Task 1: Defenitions

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- Compares one part of a group to the whole group.
Rate- A comparison of two quantities measured in different units.
Proportion- A part considered in relation to the whole.

Task 2:

  1. 5 hours to travel 360 miles is about _____mph Answer: 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.

Answer: 200m

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


First: You can do it Diagonally, you multiply the top left to the bottom right and the top right to the bottom left.

Second: You can do it vertically, you divide the numerator to the denominator for each ratios.

Last: You can divide the top left to the top right, then you divide the bottom left to the bottom right.

Task 4:

Here is a Video that will help you!

Task 5:

Ex Mortage CEO sentenced to prison for 3 years for a 3Billion dollar fraud.

Homeless man sentenced to prison for 15 years for stealing 100 dollars from a bank.

1) Does this seem fiar?

No this is not fair at all.

2) With what you know about proportion look and read what is in the image above. Does this seem just and fair?

Its not fair at all. I made this choice because the guy who stole 3billion dollars only got sentenced to prison for 3 years. And the homeless man who was starving for food and wanting to stay in his shelter got sentenced to prison for 15 years, which is 12 years longer than the CEO who stole 3billion dollars.

3) What would you have done if you were the judge?

If i was the Judge. I would let the homeless man go off with a warning because he's homeless and he needs food and he also needs money to stay in the shelter.

Thank You For Taking Time To Read My First Proportion Post!
