Gielh's Proportion Post

Ratio- A ratio is a comparison of two quantit
ies measured in the same unit.
Example: you have a bag of 33 skittles, you pour 20 in your hand . It would look like this
33/20 or 30:20

Rate - A rate is two quantities measured in different units.

Example : The rate at which you type 30 words

perminute. Another example :

Proportion- An equation which sates that two ratios are equal.
Example :

1) 5 hours to travel 360 miles about 72 mph

2) As a play group worker, if I increase the amount of apple juice I am serving at the playgroup from 25ml to 100ml, how much should I increase the orange juice to keep the quantities in the same proportion? The orange juice is 50ml to start with.

3) what are the three ways you can prove that statements are true?

Here is a video of a proportion statement

1) Does this seem fair? No because he only took 100 dollars . He could of only stayed at jail for 1 month not 15 years .

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?

Its not fair for Roy Brown Because he only took a hundred dollars then he felt guilty and the next day he surrenders to the police . Alexandria should of been jailed for 15 years instead of Roy Brown.

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

If i was the judge i would only put Roy Brown in prison for only a month.
