Extracting numerator of a Ricci tensor component

edit

Hello

I'm solving Einstein equation in vacuum. I already computed the Ricci tensor. For example, de first Ricci component is saved in the following variable eq1:

eq1=EE[0,0]

The denominator of the component should vanish since since the other part of the equation is zero. How can I extract numerator of the expression. I have tried:

eq1.denominator()

But it does not work. Thanks
