Question

A number N is multiplied by 3. The result is the same as when N is divided by 3. What is the value of N?

Answer 1

The answer MIGHT be 0, but 0/3 is also undefined.

Answer 2

Answer:

$N=0$

Step-by-step explanation:

We have been given that a number N is multiplied by 3. So our number would be $3\cdot N$.

We are also told that N is divided by 3. So our number would be $\frac{N}{3}$.

As we are told that the both results are same, so we can equate both expressions as:

$3\cdot N=\frac{N}{3}$

$3*3\cdot N=\frac{N}{3}*3$

$9N=N$

$9N-N=N-N$

$8N=0$

$\frac{8N}{N}=\frac{0}{N}$

$N=0$

Therefore, the value of N is 0.
