why is division by 0 not possible?
Answers
Answer:
Division by 0 is not possible because anything you divide with 0,you'll get 0.
For example: 0/7=0 & 3/0=0
Answer:
Dividing by Zero is undefined.
Explaination:
Dividing
To see why, let us look at what is meant by "division":
Division is splitting into equal parts or groups.
It is the result of "fair sharing".
Example: there are 12 chocolates, and 3 friends want to share them, how do they divide the chocolates?
12 chocolates 12 chocolates divided into 3
12 Chocolates 12 Chocolates Divided by 3
So they get 4 each: 12/3 = 4
Dividing by Zero
Now, let us try dividing the 12 chocolates among zero people, how much does each person get?
Does that question even make sense? No, of course it doesn't.
We can't share among zero people, and we can't divide by 0.
Another Good Reason
After dividing, can we multiply to get back again?
multiply by zero
But multiplying by 0 gives 0, so that won't work.
Once again, dividing by zero gives us difficulties!
Imagine We Could Divide by Zero
Okay, let us imagine we can divide by zero, and see what happens.
That means that things like 1/0 and 0/0 would behave like normal numbers.
Try Multiplying By Zero
So let us try using our new "numbers".
For example, we know that zero times any number is zero:
Example: 0×1 = 0, 0×2 = 0, etc
So that should also be true for 1/0:
0 × (1/0) = 0
But we could also rearrange it a little like this:
0 × (1/0) = (0/0) × 1 = 1
(Careful! I am not saying this is correct! We are assuming that we can divide by zero, so 0/0 should work the same as 5/5, which is 1).
Arrggh! If we multiply 1/0 by zero we could get 0 or 1.
In fact we can't have both possibilites, so we cannot define 1/0 to be a number.
So it is undefined.
So what is 0/0 ?
0/0 is like asking "how many 0s in 0?"
Are there no zeros in zero at all? Or perhaps there is exactly one zero in zero? Or many zeros?
So 0/0 is indeterminate (it could be any value).
In conclusion:
When we try to divide by zero, things stop making sense
That is all.
