Penjelasan dengan langkah-langkah:
1 a. 950 + 900 + 250 + 450 + 600 + 650 +750 = 4.550
b. Minggu, alasannya hari libur
c. 250 : 900 = 5 : 18
2. persen drama = 100 - (jumlah seluruhnya = 85)
= 15
15% ada 45 berarti 5% nya ada 15 orang
a. 100% = 5%(20)
= 15(20)
= 300 orang
b. semua siswa selain drama
tari = 12% × 300 = 36
voli = 20% × 300 = 60
basket = 30% × 300 = 90
PMR = 10% × 300 = 30
KIR = 13% × 300 = 39
