### A Thinking Question....

When 1 is divided by 1, the answer as we know the answer will be 1. Similarly when 2 is divided by 2, 3 is divided by 3 and 4 is divided by 4, we know that the answer will still be equal to 1.
However, is it true that when x is divided by x, the answer will always be 1? If not, when is x divided by x not equal to 1?

2. No, when x = 0, 0÷0 = ∞

3. When x=0.

Because when 0/0 = it is infinity!

XD

4. How do you even get that sign?

Oh and I agree with Millie and Jun Hui. My fault.

Let's put this in Mathematical terms.

Let x = 0

x / x = ?
0 / 0 = ?
0 / 0 = ∞

By the way, why is it infinity again?

5. If x = 0, the ans would be ∞.

If x ≠ 0, then the ans would always be 1, since x = x.

6. when x = 0

the factor would be ∞

7. When x is 0, then 0÷0=∞

8. When x is 0, then the answer will be 0÷0 = ∞ instead of 1.

9. No, when x÷x, the ans would always be 1 as long as x≠0, as 0÷0=∞

10. No, x/x will not always be equal to one. It is not equal to 1 when x is 0. This is because 0/ 0 = ∞.

11. When x is 0, then the answer will be 0÷0 = ∞ instead of 1.

13. no, when x = 0, the answer will not be 1, but ∞

14. when x is the number 0

15. when it is 0 or a negative.

16. wait, my bad, if its a negative it still is one

17. When x = 0, x/x = ∞

18. yeah... i agree with all of your...
let x be 0,
x divide by x, its infinity... Cannot be solved...

19. But in algebra, the unknown is not usually 0. But in this case x=0, because it is the only value in which this principle applies to.
