Translation:Silver is more expensive than iron and copper.
Halo teman-teman! In this sentence, the pronunciation of "perak" sounds with the final "k". Actually, the sound of this word is pronounced better when hearing it alone, with "k" as a glottal stop" So, this would be: PE-ra(glottal stop) lebih mahal...
I think, this could be sometimes pronounced fast, for example with the three words in a row: Pera-lebih-mahal (without any pause between them), and the same for the other four words: daripada-besi-dan-tembaga
I hope it helps.
Selamat belajar! :)
