Years ago, I had a developer actually ask me how to evaluate percentages, lol.  He knew how to do it if it was a ten question quiz.  He literally stepped through case score is 10, then 100...case score is 9, then 90, etc.  The problem was there were 11 questions.  LMAO.

I've been a developer for over 30 years and I've had my share of brain farts.

Addition, subtraction is 3rd grade math, multiplication and division 4 th grade and converting fractions to decimals is 4th or 5th grade math. Fractions have upper number called numerator and lower number caller denominator, remember? You use your division skills and divide the numerator (upper number) by the denominator (lower number or divider) to equal decimals. 

This is elementary math not high school level math.

Don't know why everyone wants to teach @ghost how to figure it out...just Google it!

 

You can even ask your phone & it'll answer

Indeed. Just ask Siri what 0/0 is!

 

Anyway, for our US unit lacking, metric using brethren, I made a table showing the gram equivalents just in case we're outside of the United States, lol.

 

U-S-A! U-S-A! U-S-A! lol.

Quiz; what is more 2/5 or 3/5? Use you hand and count your fingers, including the thumb, each digit is 1/5.

For those who immediately started to perform division...there may not be any hope left for you, lol.

Thank you Islandbass! That is what I was looking for.

You’re welcome. 

 

In tomorrow’s lesson we’ll cover how to compute factorials and how to calculate the slope of a line given two points, lol. 

IB, um, you had me at you're welcome...

 

Good fishing Bruddah!

Thanks for hanging in there with us nerds!

The easiest way for the op. with the bottom number being a whole ounce is to cut the bottom number in half. Half of 5 is 2.5 so 2/5 is just under a half ounce and 3/5 is just over a half ounce. If your trying to stay roughly within your rods guidelines. Not exact math but close enough. 

Geniuses to compare two fractions? We're doomed!

 

I was actually having a protracted conversation about reality and existence with someone recently, (began with electoral college math and how each one represents a different number of voters, and went down hill from there) where I proposed that numbers aren't the universal language at all, but rather that they don't actually exist. Too long to get into here, but concluded discussions of the potential for  yet to be defined AI abilities which may encompass non computational calculations, and how we as a species will or won't keep up. Any how, It is rather easy to experimentally without math figure out which of 2/3 or 3/5 is larger (or any other quantities). Take some string, a liquid or some putty, divide or separate into equal parts equal to the number to the right of the /. Now take the same number as on the left of the / and compare which is bigger. You'll also have a visual as to how much bigger. I used leggos and Pizza to teach my nieces and nephew basic math concepts, and I found, often the visual of what the numbers represent often made the learning quicker. Now don't get me started on why the weight of plastics is irrelevant (cause it is)...

Congrats @reason, you invented common core, or "new math."

weight of plastics

I think you meant mass, here.

Are you inviting me to go fishing on the moon?....  

That's no moon....

Too true, lol.

 

With regard to weight, no fat jokes, lol. Besides, what really matters is what planet or other celestial body you're on. One way to lose weight with no effort on your part is to go to another planet whose mass is significantly less than the earth. Can't promise you'll survive, though. Weight matters, lol!

 

The calculate the slope given two points was from real life. My youngest is learning this stuff right now. That is the only reason why it's relatively fresh in my mind. It's been well over 40 years since I've learned fractions and other elementary math, but my teachers were good and passionate and their lessons stuck. I can see a fraction and know it's decimal equivalent for the most common ones like I was still in 3rd grade.  They burned those concepts into my mind, lol. 

 

Trigonometry next week.  ?
