I'm having difficulty in understanding beta plus decay. How can a proton which has slightly less mass than neutron transform into a neutron, positron and neutrino?

Form where does the extra mass for neutron,electron and neutrino come? Is it that during the decay some of the binding energy gets converted into mass?
