*Proportion*

Task 1

Rate: A rate compares 2 quantities measured in 2 different units

Proportion: An equation which states that 2 ratios are equal.

Task 2

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?

Task 4

Ratio:

**The relation between two similar numbers with respect to the number of times****the first contains the second.**

Rate: A rate compares 2 quantities measured in 2 different units

Proportion: An equation which states that 2 ratios are equal.

Task 2

- 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 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**

**One way to prove that this is true is when you cross- multiply, vertical and**

**horizontally**

**they all have the same answer. Here is one of the ways to do it.**

**4/9=16/32 is false because if you do the same thing you get different numbers to divide it by so it is false. Here is a quote so you can better understand it" Whatever you do to the top you must do to the bottom".**

Task 4

Here is a proportion video to help you cross-multiply

Task 5

- Does this seem fair? To be it does not seem fair because the homeless guy only stole $100 and turned himself in and the other guy stole 3 billion
- 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 would have given the homeless guy only 1 year or maybe even less because he confessed but the mortgage guy would about 30 years.
