Consider the following code:

x = 0; y = 0;
a = Dynamic[x = x + 3]; b = Dynamic[y = y + 2];

I need to display the value of

N[a/b]

It's not clear what the question is.

I am sorry, I edit the post.

When we define two dynamic values, say a and b as above, I need to express the operation a/b in numerical form, but N[a/b] does not work !

I wondering to know how we can do this.

Both a and b are expressions with head of Dynamic. Maybe you want to work directly with the values {x,y}? Could be done as follows.

x = 0; y = 0;
Dynamic[x = x + 3; y = y + 2; N[x*y]]

I changed the division to multiplication so that changes in the value would be visible.

Thank you for your help Your suggestion works well for me.

Maybe something like this will be a littel help.

.inputmaxnumber[max_] := Manipulate[x, {x, 0, max, 3/2*00.1}] // N inputmaxnumber[100]

And here you will just need to enter a max value of max as a number.
