WhAT IS A NUMBER DIVIDED BY ZERO (0)?

Answer 1

x/0 = infinity
It can be demostrated in the following example.
let x be 10 for example.
when 10 is divided by 5, the answer is 2.
when 10 is divided by 4, the answer is 2 and 1/2.
when 10 is divided by 3, the answer is 3 and 1/3.
when 10 is divided by 2, the answer is 5.
when 10 is divided by 1, the answer is 10.
when 10 is divided by 0.1, the answer is 100.
when 10 is divided by 0.01, the answer is 1000.
when 10 is divided by 0.001, the answer is 10000.
Therefore, when 10 is divided by 0, the answer is infinite.
You can notice that as the denominator decreases, the answer gets larger. So, when the denominator approaches 0, the answer would be infinite.

Answer 2

Goodness. All of the answers given are incorrect.

A number divided by zero is NOT infinity.

These answers can be understood because as you divide by smaller and smaller numbers, the result continually increases. However, dividing by zero does NOT result in infinity.

Division by zero is UNDEFINED. By the definitions of division, and of zero, such a statement makes no logical sense. Hence it really, really, really, is undefined.

Answer 3

a/0 is undefined.

However, if you're familiar with the concept of a limit, then the limit of a/x as x approaches 0 is +/- infinity, depending upon whether x is approaching 0 from the negative or positive side.

As an example, if x = .000000001, a/x is quite large, and will get larger as x gets even smaller (approaching 0). However, you must distinguish bewteen x -->0 and x = 0.

Answer 4

You can't do it. mathematically, division by zero is not defined, just like multiplying by infinity.

You can, instead, look at the limit of a sequence, such as 1/x as x tends to zero. We say that this tends to infinity. It might sound like i'm being pedantic, but it's a very important distinction.

A lot of first year university mathematics deals with this very distinction, by carefully defining things like this. Without such careful definitions, higher level maths can become a mess.

Edit:

I'm sure that TSR21 below carefully read what I wrote when he said 'All the above answers are incorrect..."

Answer 5

Undefined

Answer 6

no number is divisible by 0.hence any number /by 0 becomes infinity

Answer 7

the number itself or :
x/0=infinity

Answer 8

graphically, infinity.
arithmetically, undefined

its like dividing a pie amongst nobody!

Answer 9

undefined

Answer 10

INFINITY!
