How do you show yourr work for finding 5/6 of 18?

To be honest, I feel like this is an illogical question, but I'll still be doing this.

 

When finding something of something, we just multiply it. So finding 5/6 of 18 is just doing:

5/6 * 18 

When evaluating this we get:

90/6 = 15

 

So the answer is 15, and the work for it is above.
