Penjelasan:

yang bagian pertama maaf kalau banyak salah salah soalnya agak kurang paham sama kalimat yang suruh active or passive

yang ke2 jg maaf kalo kurang teliti gitu

trs kalo yang bagian ke3, di brackets nya cukup keliatan verb dan rumus apa yg dipakai, jadi kita tinggal ngubah aja ke rumus passive voice, kaya contohnya di nomor 1, english disini as a subject (it) lalu understand itu keyword nya, subject kalau ketemu verb 1 itu simple present tense, passive voicenya simple present tense itu is/are (tergantung subject) + v3 + by, sisa rumus lainnya bisa di search di google juga kok, semangat
