There is not enough information to calculate the percentage yield.
The atom economy is 100 %, defined by
(wanted product atoms / reagent atoms) * 100
= (3/3) * 100

A reaction may have a great %yield because almost all of its reactant turn into products. But it may have a low atom economy because the majority does not turn into the product that you want (i.e. it turns into by-products or heat) industry try and counter-act this by using the by-products (or heat) in other reactions or to catalyse reactions, or may even sell the by-products.
