A study of Bc+→J/ψDs+B_c^+ o J/psi D_s^+Bc+​→J/ψDs+​ and Bc+→J/ψDs∗+B_c^+ o J/psi D_s^{*+}Bc+​→J/ψDs∗+​ decays using 139 fb−1^{-1}−1 of integrated luminosity collected with the ATLAS detector from s=13sqrt{s} = 13s ​=13 TeV pppppp collisions at the LHC is presented. The ratios of the branching fractions of the two decays to the branching fraction of the Bc+→J/ψπ+B_c^+ o J/psi pi^+Bc+​→J/ψπ+ decay are measured: B(Bc+→J/ψDs+)/B(Bc+→J/ψπ+)=2.76±0.47mathcal B(B_c^+ o J/psi D_s^+)/mathcal B(B_c^+ o J/psi pi^+) = 2.76pm 0.47B(Bc+​→J/ψDs+​)/B(Bc+​→J/ψπ+)=2.76±0.47 and B(Bc+→J/ψDs∗+)/B(Bc+→J/ψπ+)=5.33±0.96mathcal B(B_c^+ o J/psi D_s^{*+})/mathcal B(B_c^+ o J/psi pi^+) = 5.33pm 0.96B(Bc+​→J/ψDs∗+​)/B(Bc+​→J/ψπ+)=5.33±0.96. The ratio of the branching fractions of the two decays is found to be B(Bc+→J/ψDs∗+)/B(Bc+→J/ψDs+)=1.93±0.26mathcal B(B_c^+ o J/psi D_s^{*+})/mathcal B(B_c^+ o J/psi D_s^+) = 1.93pm0.26B(Bc+​→J/ψDs∗+​)/B(Bc+​→J/ψDs+​)=1.93±0.26.
