Elijah's Proportion Post

Ratio- Relation between two simiplar numbers (2:6)
Rate- A comparison of two quantities measured in different units (60km/hr)
Proportion- An equation that states two ratios are equal
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.
You should increase by 2x.
What are the three ways you can prove that equivalent ratio statements are
3/4 = 12/16
1. Does this seem fair? No, because the homeless man only stole $100 and he turned himself in the next day and has 15 years in jail but the billionaire dude only has 40 months but he stole 3 billion dollars.
2. It isn't fair because the rich dude should spend more time in jail because he stole alot of mula but the homeless guy only stole 100 bucks and he's got 15 years.
3. I would put the rich dude in jail for how much money he stole and I would only put the homeless guy in jail for only a year or so because he only stole 100 dollars and he turned himself in.
