This is your proof that ZF is inconsistent, is it?

It means that d is not a terminating fraction, you moron, so d is
not part of the set of all terminal fractions and hence you haven't
shown that *this* enumeration is not surjective, much less that the
set of terminal fractions is uncountable.

You are incapable of very basic mathematical reasoning. You are a
shame to your school.
