  Meadows are alternatives for fields with a purely equational axiomatization.
At the basis of meadows lies the decision to make the multiplicative inverse
operation total by imposing that the multiplicative inverse of zero is zero.
Divisive meadows are meadows with the multiplicative inverse operation replaced
by a division operation. Viewing a fraction as a term over the signature of
divisive meadows that is of the form p / q, we investigate which divisive
meadows admit transformation of fractions into simple fractions, i.e. fractions
without proper subterms that are fractions.
