AB  - A measurement of four branching-fraction ratios for three-body decays of B mesons involving two open-charm hadrons in the final state is presented. Run 1 and Run 2 pp collision data are used, recorded by the LHCb experiment at centre-of-mass energies 7, 8, and 13 TeV and corresponding to an integrated luminosity of 9 fb(-1). The measured branching-fraction ratios are<disp-formula id="Equa"><mml:mtable displaystyle="true"><mml:mtr><mml:mtd><mml:mfrac>B<mml:mfenced close=")" open="(">B+-> D+D-K+</mml:mfenced>B<mml:mfenced close=")" open="(">B+-> D<overbar></mml:mover>0D0K+</mml:mfenced></mml:mfrac>=0.5170.0150.013 +/- 0.011,</mml:mtd></mml:mtr><mml:mtr><mml:mtd><mml:mfrac>B<mml:mfenced close=")" open="(">B+-> D-D+K+</mml:mfenced>B<mml:mfenced close=")" open="(">B+-> D<overbar></mml:mover>0D0K+</mml:mfenced></mml:mfrac>=0.577 +/- 0.016 +/- 0.013 +/- 0.013,</mml:mtd></mml:mtr><mml:mtr><mml:mtd><mml:mtable><mml:mtr><mml:mtd><mml:mfrac>B<mml:mfenced close=")" open="(">B0 -> D-D0K+</mml:mfenced>B<mml:mfenced close=")" open="(">B0 -> D-D0K+</mml:mfenced></mml:mfrac>=1.754 +/- 0.028 +/- 0.016 +/- 0.035,</mml:mtd></mml:mtr><mml:mtr><mml:mtd><mml:mfrac>B<mml:mfenced close=")" open="(">B+-> D+D-K+</mml:mfenced>B<mml:mfenced close=")" open="(">B+-> D-D+K+</mml:mfenced></mml:mfrac>=0.907 +/- 0.033<mml:mo>+/- 0.014<mml:mo>,</mml:mtd></mml:mtr></mml:mtable></mml:mtd></mml:mtr></mml:mtable><graphic position="anchor" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="13130_2020_14428_Article_Equa.gif"></graphic></disp-formula><p id="Par2">where the first of the uncertainties is statistical, the second systematic, and the third is due to the uncertainties on the D-meson branching fractions.
