The Wrong Way To Reduce Fractions. But It Works Sometimes

This is a joke video about mathematical coincidences. I solved a bunch of fractions problems but my teacher didn't like my answers even though the results were 100% correct.

It's called anomalous cancellation.

I LOVE that you said "my teacher clearly hates me" because this perfectly describes these sorts of mentalities!

[nathanbeer]

The dark secret that teachers don't want us to know.

It's hilarious how some people think that this video was being serious and are all triggered in the comments. READ THE TITLE AND DESCRIPTION, PEOPLE!

[lostlong]

Lesson learned: People take things way too seriously... It's so obvious that he made this video so we could get a laugh, considering that the other content he posts are very serious and further into math than this simple video of "reducing fractions".

“For the fifth problem, ”
*moment of silence*
“I looked at...”

[Niko_demus]

The only interesting question is "why does it work?" and it's not even asked.

[malte]

You don't knoow why? But he talked to you after class.

[TimJSwan]

Your teacher should have given you extra credit for finding out that his set of example problems were perfectly broken.

[alpistein]

Guys lets just put it this way: There's a reason why he chose these specific fractions. For all of you saying this is misleading, look at the goddamn title. "The wrong way to reduce fractions." That's a statement, he's telling you it is wrong. "But it works?" That's a question, he's asking if it works or not. It is meant to arouse your curiosity, he's not trying to mislead you. Chill out.

Congrats, you've managed to make the video with the most disgusting and ignorant comment section I've ever seen. Great video, though. Keep it up!

This happened while I was tutoring a kid. We were trying to find the area of a regular pentagon. And the answer was like... 5.23...something, but rounded to 5.2. He got an answer of 5.18...something, randomly, by doing something incredibly stupid. I then told him he was wrong, even though he had the right answer. He got really heated, and kept telling me, "BUT I HAVE THE RIGHT ANSWER, HOW THE HELL AM I WRONG???"

[amichaelthomas]

The more interesting question is what percentage of fractions within a certain range (of denominator and numerator) satisfy these conditions.

[nixdorfbrazil]

Ok... So it "works"... but I don't understand why it "worked". I read the Wolfram link, and still doesn't make any sense. Is this just a mathematical coincidence? Or there's some logic behind it?

[sniperfuazo]

lol
it work
but your teacher just hate you for being way too smart

[Vazhaspa]

Yes that is exactly correct!! We know that Max Planck was once working on a "fraction" over a function of r [namely f(r)], so he canceled out "f &r" from numerator and denominator and arrived at the quantum of "action"!

[jojogape]

Even though this is obvious to a lot of people... you should have explained that these are just coincidences, and the rule very rarely works. We're used to finding "Videos With Revolutionary Methods To Solve Math Problems" so a lot of people might end up believing this video no matter how incredible it is.

I mean, the moment they told me the sum of every positive number was -1/12 I just gave up.

Edit: I see the title now. I don't know if you recently changed it though. Anyway, good thing somewhere you can see that this method is wrong.

[akbaer]

This is really hilarious

At the first glance, i thought this was a serious video. Then I realized this was all just a joke and a coincidence.

[alexzuma.]

teachers be like: your answer IS correct, but, you simplified those numbers the wrong way!

[brucewaters]

ITS A JOKE EVERYONE CHILL YOURE ALL HATERS OF COURSE IT DOESNT WORK

[yokowasis]

Because the most important thing is not the result, but the process.
