bantu plis buat besok :) semua nya kalo gk bisa ya pilih nomer aja

Sorry bisanya sampai nomor 3 aja

1. Rudi = 2/5 × 35 = 14 buku
Fikri = 3/5 × 35 = 21 buku
2. A : P = 45 : 40 = 9 : 8
3. Risma = 6/15 × 750.000 = 300.000
Annisa = 9/15 × 750.000 = 450.000
4. Alika = 2/3 × 90.000 = 60.000
Nadia = 1/3 × 90.000 = 30.000
• 60.000 - 30.000 = 30.000
5. Skala = JP/JS = 10 cm/250 km = 10/25.000.000 = 1/2500000 = 1:2.500.000
6. PS = 5 : 1/250 = 5 × 250/1 = 1250 cm
7. JP = 14 × 1/200 = 14/200 = 0.07 m = 7 cm
