Question

what is zero divided by zero?
Which of these rules should i apply?
(a)any number divided by itself the ans is one
(b) any number divided by 0 the ans is infinity.
(c)any number divided by 0 the ans is 0

Answer 1

B.

Answer 2

All the answers are equally good (or bad) as they follow a pattern. For (a) you are looking at the pattern 1/1=1, 2/2, =1, 3/3=1, and so it makes sense to say 0/0=1. For (b) consider 1/0=infinity, 2/0=infinity, 3/0=infinity, etc. so it makes sense to say 0/0=inifinity. For (c) use 0/1=0, 0/2=0, 0/3=0, etc. so 0/0=0. But the truth is you could get any answer using a similar logic. For example 2/1=2, 4/2=2, 6/3=2 (notice the numerator is always twice the denominator), so you could conclude that 0/0 should be 2. You could do something similar to get any number you want out of 0/0. Thus, we say that 0/0 is undefined, not because it isn't possible to do, but because there are an infinite number of choices that might make sense (follow a pattern). We don't know how to choose one.

Answer 3

0/0 is undefined or infinity, apply rule (b)

Actually 0/0 is not a real number, that's why when you use the calculator to solve this, you cannot get any answer but error. The reason why it is infinity or undefined is that you cannot actually determine how many zero are there in 0, its quite a big number that you cannot comprehend. Its infinite

Answer 4

None of these answers are true for your question because YOU CANNOT DIVIDE BY ZERO - it is an undefined value. (If you do it on a good calculator, it will give you some sort of error message.) But, of the choices you stated, A is the only valid statement: any NON ZERO number divided by itself is one. B is incorrect: any number divided by zero is UNDEFINED, not infinity. C is just plain wrong.

Answer 5

Undefined, since division by zero is not allowed in mathematics.

15 divided by zero is what?
How many empty things will add up to 15 so you can prove your answer.
Zero times 1 is still zero
Zero times 87 million is still zero.
No number times zero will add to 15, so...undefined.

You might argue zero time zero is zero, so it's true. But so is any number times zero equal to zero, so are you going to say all numbers are equal to each other?

Is zero a number? Consider the following scene:

Ernie: I've put a number of cookies in that Jar. You can have them if you give me your teddy.
Bert: Great
While Ernie hands over the teddy and looks eagerly in the jar, said:
Bert "Wait a Minute There's No Cookies Here. You Said You Put a Number of Cookies in There"
Ernie: That's right, zero is a number.

Answer 6

any number divided by 0 is 0. So 0 divided by 0 is 0

Answer 7

None of those rules apply. (The second two are incorrect.) Any number divided by 0 is undefined. 0 divided by 0 is undefined as well.

Answer 8

You fool!

Dr. Science proved that dividing by zero will invoke a tear in the space-time continuum that will allow monsters from alternate realities a portal to enter this world and take it over, dooming mankind to a lifetime of servitude.

Put the pencil down and back away from the math problem.

Answer 9

The best answer is B. You cannot divided something into zero parts. Law of conservation of mass.

Answer 10

None of the above. Zero divided by zero isn't merely "undefined," it's undefinable; i.e., indeterminate.

0/0 = just about anything, depending on where it occurs.

Answer 11

anynumber divided by 0 is infinity
