X/y=z

prove that 13/12=2???

this is nonsense.

Of course 13/12 is not 2

You want to fix up your question a bit?

My friend ask me to do it so i jus asked if it were possible but what about 13/11 can it be equal to 2???

Yes, 13/11 = 2

XIII
----- = II = 2
XI

That works the same way as
12/2 = 7
XII. Now draw a line half way down do you leave a VII on top and VII is 7.

Oops. I thought we were doing serious math homework here.

My bad :-(

Like 16/64 = 1/4 because you can just cancel the 6's.

To prove that 13/12 is equal to 2 using the equation x/y = z, we need to substitute the given values into the equation.

Step 1: Substitute the values
We have x = 13, y = 12, and z = 2. So, the equation becomes:
13/12 = 2

Step 2: Simplify
To simplify the equation, we can multiply both sides by 12, which is the denominator of the left side:
(13/12) * 12 = 2 * 12

On the left side, the 12s cancel out:
13 = 2 * 12

Step 3: Calculate
Multiply 2 by 12:
13 = 24

Step 4: Evaluate
Since 13 does not equal 24, we can conclude that 13/12 does not equal 2. Therefore, the statement 13/12 = 2 is incorrect.
