Abstract Very recently the MACHO Collaboration published detailed data for 45 double-mode Cepheids in the Large Magellanic Cloud. Here we compare these data with new stellar pulsation models. We conclude that the new period ratios are in good agreement with a metal content Z = 0.005 – 0.01 in the Large Magellanic Cloud.
