Question: Applying chain functions

Hello guys,

From time to time I use the procedure below to chain functions to the right of the expression to be evaluated.


For example:

(sin(x)^2+cos(x)^2)&/simplify                      1

For functions that work with just one argument, it's okay, but with functions that take more than one argument (like convert, subs), I don't know how to implement it.

0.76&/ convert(???,fraction)


If someone more experienced can help, I'd be very grateful.
