9x/2x

x11
x7***
7
x5

9 x / 2 x = 9 / 2 = 4.5

To simplify the expression 9x/2x, we can cancel out the common factor of "x" in the numerator and denominator. This leaves us with:

(9x)/(2x) = 9/2

So the simplified version of 9x/2x is 9/2.

Now let's move on to the next part of your input, "x11". It seems like you're writing a mathematical expression that includes the variable "x" and the number "11". However, it's not clear what operation you want to perform with them. If you provide more information or clarify the intended operation, I can help you further.

Similarly, for "x7***", "7", and "x5", it's unclear what specific operations you wish to perform. To get accurate answers, please provide more details or specify the desired mathematical operations.
