now im not a big maths freak, but me and my freind were talking, and we found this problem in maths:


1/3 of 100 = 33.333333333333333333

which means:

2/3 of 100 = 66.666666666666666666

and therefore:

3/3 of 100 = 99.9999999999999999999

HOW CAN THREE THIRDS OF 100 BE 99.9?? PLEASE EXPLAIN SOMEONE =D

3/3 = 1

...modes and scales are still useless.

because a base-ten numbering system (our numbering system) can't be divided into 3rds evenly, so calculators just get as close as they can

also, it took you this long to figure that out? wow.

because 1/3 is 3,33333 + a number/amount between 3 and 4.

The math you use is basic math. With advanced math they found ways of this, and they don't work so much with amounts, but with formula's.

1/3 of x would just stay as 1/3. The amount in numbers is irrelevant. In math it's about the logic and not the outcome.

(the logic being it's just 1/3 of 100).

try it with a calculator. it gives you 99.9

Instead of trying it with a calculator, you should work it out with a pencil.

3.333333333333333 = 3
6.666666666666666 = 7

3 + 7 = 10


that's my logic, I understand it's most likely flawed but I don't really mind, rounding just makes everything so much easier for this problem.

That's the point. In England, and the whole of the UK (not sure about anywhere else) it's called "maths", not "math". So, what with the language being called ENGLISH, "maths" is correct, and "math" is not.

99.999999999999999999999999999999999999999999999999999999999.... is a recurring number. It follows logically that if there was an end to it, it would resolve as 100. We learnt that in the first year of highschool (age 11) so apologies if my explanation isn't 100% obvious. BAsically, 99.999999...etc = 100
#29
yeah...
3/3 of 100 is 99.999999999999 but it also can be 100.
Yeah you won't get it but my maths teacher told this to us 2 weeks ago.
Dude get with it,

1) It's actually because 99.(9) in maths means 100. The point is that x.(9) = x+1
Basically in maths x.(3) and x.(6) constitute as numbers, whereas x.(9) already constitutes as x+1.
And (9) means that it stays in a period, basically after the comma, there is an endless quantity of nines or whatever number is in the brackets.

Proof:

4.(9)=5

x=4.(9)
10x=49.(9)
10x-x=49.(9)-4.(9)=45
9x=45
x=5
4.(9)=5

Whereas 4.(3)=4.(3)

x=4.(3)
10x=43.(3)
10x-x=43.(3)-4.(3)=39
9x=39
x=4.(3)
4.(3)=4.(3)

And 4.(6)=4.(6)

x=4.(6)
10x=46.(6)
10x-x=46.(6)-4.(6)=42
9x=42
x=4.(6)
4.(6)=4.(6)


2) Furthermore, if you take 3/3 as 1 then 1*100=100.

3) And to further explain your problem, you should also look at it like that:

1/3 of 100 is 33+1/3
2/3 of 100 is 66+2/3
3/3 of 100 is 99+3/3=100

Hope that helped.

Technically, 3,3333333333 is not 1/3.

There are 3 math systems that I know off (I don't know much math)

which is numerals; 1 + 4 - 6 x 5
Dividing; 1/3, 5/6
Formula's; xa + b = y (this 1 being the most accurate one)

We human made that up because it's easier to use, but if you really want to get ass-like, then 33,33333333 is not 1/3 of 100.

It's the human "representation" (for the lack of better word) for 1/3 in numerals.

Numbers are made up by humans and math isn't.

May sound strange but it's true.

Math is just how everything works together, while numbers is a visual (numeral) representation for us humans.

33,33333 is just a flaw in human representation of math, because we fail.

1/3 is the most accurate.

tl;tr
Just continue on, on school until you use formula's and understand that advanced math is more accurate then kindergarten meth.

I remember the days when I was out at the playground and we all sat cross-legged, waiting for our turn at the bubble.
It explains why kindergarteners are always so jumpy.

What I'm surprised about is how half the people in here say that 3/3 (or 3 divided by 3) equals .999etc...

You do not need to round or use any kind of complicated math. This is simple arithmetic. A number divided by itself equals 1 no matter what.



EDIT: How old are you? I learned the basics to fractions/irrationals/divisions/ when i was in 1st grade.*


*My teacher taught us this stuff even though school curriculum didn't include it until i was probably 11 (6th grade)

33.3 recurring is only to a certain degree of accuracy. Like 0 could be 0.00001 or 0.0002 etc etc. 0 is not necessarily nothing.
