buatkan kalimat passive voice and active voice: 1.roy went to jakarta by plane 2.my father will call me at 3 o'clock. 3.there are 2 girls in the class

Nomor 1 tidak mempunyai objek, sedangkan nomor 3 adalah kalimat nominal, jadi tidak ada kualimat passive-nya

2. I will be called by my father at 3 o'clock

Semoga membantu ^-^
