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?

Respuesta :

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

Answer:

[tex]N=0[/tex]

Step-by-step explanation:

We have been given that a number N is multiplied by 3. So our number would be [tex]3\cdot N[/tex].

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

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

[tex]3\cdot N=\frac{N}{3}[/tex]

[tex]3*3\cdot N=\frac{N}{3}*3[/tex]

[tex]9N=N[/tex]

[tex]9N-N=N-N[/tex]

[tex]8N=0[/tex]

[tex]\frac{8N}{N}=\frac{0}{N}[/tex]

[tex]N=0[/tex]

Therefore, the value of N is 0.
