Using the form factors of the transitions $\\Upsilon(nS) \\to B_{(c)}$ obtained from the CLFQM, we calculate the branching ratios of the decays $\\Upsilon(nS)\\to B_{(c)}\\ell\\nu_\\ell$ and $\\Upsilon(nS)\\to B_{(c)}M$ with $\\ell=e,\\mu,\\tau$ and $M$ referring to $\\pi(\\rho),K^{(*)},D^{(*)},D^{(*)}_s$.
