Jawab:

Penjelasan dengan langkah-langkah:

[tex]1. a) Petani = \frac{145}{360} x 720\\\\=145 x 2 = 290 orang\\\\ b) Nelayan = \frac{90}{360} x 720\\\\=90 x 2 = 180 orang\\\\ c) PNS = \frac{45}{360} x 720\\\\=45 x 2 = 90 orang\\\\ d) Pedagang = \frac{80}{360} x 720\\\\=80 x 2 = 160 orang\\[/tex]

[tex]2. a) IPA = \frac{25}{100} x 40 = 10 siswa\\\\b) Pkn = \frac{10}{100} x 40 = 4 siswa \\\\c) IPS = \frac{15}{100} x 40 = 6 siswa\\\\d) Bahasa Indonesia = \frac{25}{100} x 40 = 10 siswa\\\\e) Matematika = \frac{(100-75)}{100}x 40 =\frac{25}{100} x 40 = 10 siswa[/tex]

3. Siswa TK = 8 x 20 = 160 siswa

siswa SD = 9 x 20 = 180 siswa

siswa SMP = 5 x 20 = 100 siswa

siswa SMA = 6 x 20 = 120 siswa

a) selisih siswa SD dan TK = 180 - 160 = 20 siswa

b) Jumlah siswa SMP dan SMA = 100 + 120 = 220 siswa
