We investigate the decays of , and into plus a scalar or vector meson in a theoretical framework by taking into account the dominant process for the weak decay of 
meson into and a 
pair. After hadronization of this component into pairs of pseudoscalar mesons we obtain certain weights for the pseudoscalar meson-pseudoscalar meson components. In addition, the and decays into and 
, 
are evaluated and compared to the and 
production. The calculation is based on the postulation that the scalar mesons 
, 
and 
are dynamically generated states from the pseudoscalar meson-pseudoscalar meson interactions in S-wave. Up to a global normalization factor, the 
, 
and 
invariant mass distributions for the decays of 
, 
, 
, 
, 
, 
and 
are predicted. Comparison is made with the limited experimental information available and other theoretical calcualtions. Further comparison of these results with coming LHCb measurements will be very valuable to make progress in our understanding of the nature of the low lying scalar mesons, 
and .
