Motivated by resonant x-ray scattering experiments in cuprate ladder materials showing charge-order modulation of period \ensuremathλ=3 and 5 at specific hole densities, we investigate models involving the electronic t\text\ensuremath-J ladders and bosonic chains coupled via screened Coulomb repulsion. Extensive density-matrix renormalization-group calculations applied to the ladders/chains supplemented by a self-consistent mean-field treatment of the interladder/chain coupling provide quantitative estimates of the charge order for \ensuremathλ=3, 4, and 5. As previously proposed, such patterns correspond to the emergence of pair density waves which stem from the strong electronic correlations. We comment on the existence of a \ensuremathλ=4 modulation not seen so far in experiment.
