jadi,jumlah siswa laki laki ada 18

*maaf kalo salah,,ini semampu saya,*

1) %laki2 = (48 - 30)/48 x 100%
= 18/48 x 100%
= 37,5%

2) 7 1/2 : 5 = 15/2 : 5 = 15/2 x 1/5 = 3/2 kg

3) 12 x 2 1/3 : 24 = 12 x 7/3 : 24 = 7/6 kg

4) 9/9-4 x 35 = 9/5 x 35 = 63

5) p = 1.500.000 x 38cm
= 57.000.000 cm
= 570 km
