How is 33.33 13 of 100?

Post » Tue Aug 14, 2012 3:57 pm

If you do the math, 33.33 times 3 is 99.99 which is Not 100. Can someone explain this sorcery? My best guess is the Illuminati...

33.33333... (repeated) is 1/3 of 100. The decimal doesn't end at two 3's, they continue infinitely, as far as I remember.

How? No matter how far it goes it will always end in a .9.

well we could all take it literally and stand around adding an infinite amount of .333333-etc. to the end of something when we wan't to call it 1/3. or we can just round up a slight amount and continue on with our daily life.

But if that goes for infinity, than the difference between 99.99(repeating) and 100 is literally unmeasurable.

If you use 33.34, it's not one third either. Neither is 33.333334. Ending it with a 4 is always too big, and with a 3 is always too small. It goes on infinitely, which is tiresome to write out on math homework, so we either just state fractions (1/3), or if writing it as numbers, just keep rounding it down. 3 or 4, it always rounds down to a .3, so that's what it's represented with.

It's called rounding to a non-infinite number.

If you want confusion, try working with multiple infinites of varying sizes.

I forget what its called, but there is some math proof that 0.999* = 1.0

Hence, 99.999* = 100.0


Its a trick to do with infinity.


In the case of computers, numbers cannot be infinite, so repeating decimal numbers like 1/3 are calculated by using a rounded value that is rounded far enough along that it doesn't matter. Its the same thing as Pi, nobody can calculate it's full length (since its infinitely long) so they just use a version of it that is accurate enough for whatever the calculation is.

For any two distinct real numbers, there are an infinite amount of real numbers between them (between 1 and 2 you have 1.5. 1.55. 1.555 etc on for infinity, and then between each of those there is another infinite number of numbers)

There is no number between 99.999... and 100, therefore 99.999... = 100

It's just a flaw in base-10 math. If it bothers you, you can always switch to a different base numbering system that doesn't have the problem *though it'll have a different one probably)

Due to how the decimal works.. People normally says 33.34 is 1/3 of 100 which still isn't really true.. I prefer to say 33-1/3 or 33.33-1/3.

33-1/3 x 3 = 100. 33.33-1/3 x 3 = 100.. Basicly, when you times the 1/3 by 3, it'll add an extra 1 to the last number which then bring it up to 100.
(33x3 + 1/3x3)
(99 + 1)
(100).

Basicly, I think 33-1/3 would be best thing to say..(0.33-1/3 if out of 1)

(0.33x3 + 0.00-1/3x3)
(0.99 + 0.01)
(1)

Just bust out the long division like we did in grade school. Divide 100 by 3 and see what you get, I'll wait :)

Humans can comprehend an infinite number of 3's after a decimal, and how that comes to 1/3, unless they choose not to. As da mage pointed out, computers don't have that choice. You really are more clever than your school calculator. Don't choose to 'think' like it.

According to Calculatorforfree.com it equals....33.333333333333336...What?

This forums requires that you be 13 or older to join. Thus there is no excuse for you not knowing the answer to this.

Unless you're terrible a math. Alot people here are terrible at history. Or maybe our schools are terrible at history.

QUICK, who was the leader of the French Revolution? (1789)

Imma guess Robespierre and since I didn't double check with Google, I'm risking an epic fail. Anyway all we're taught here is Canadian history. :dry:

^^Never mind he beat me to it. If it's wrong the epic fail is on him. :happy:

There is no number between 99.999... and 100, therefore 99.999... = 100

More or less this.

Here's another way to look at it. Consider the infinite sequence S1 = (1 - 0.1) = 0.9, S2 = (1 - 0.01) = .99, S3 = (1 - 0.001) = .999, ..., Sn = (1 - (1/(10^n))). As n gets increasingly large, Sn gets closer to 1. Now pick an arbitrary number E, some number that you think is as close to 1 as you can get. Notice that you can easily make (1 - Sn) be smaller than (1 - E), for some n.

Basically, the point here is that Sn can get as close as you like to 1. The limit of Sn is 1. But .99999... just is the limit of Sn (by definition).

I got backup.


Robespierre 1789, Napoleon Bonaparte led the next revolution.

It's kinda Robespierre.

It's really a trick question because there wasn't really a centralized leader - rather a Committee. Robespierre joined after and became prominent.

There was no next Revolution. He declared himself Emperor and attempted to destroy the Republic - ultimately he was against the Revolution. He was as worthless politically as Louis XVI

Well, when I say revolution, I really meant a military coup.


And Robespierre was the only real leader. Until he started the Terror that is...

Then he was killed, and there was no leader...


And then came Napoleon...
