tolong di jawab ya no 9 dan 10 oke makasih

9. 1gelas = 1/6 liter air
12gelas = 1/6 x 12 = 2 liter air

10. Misalkan A = Perempuan, B = Laki-laki
; A+B = 40,
A= 60% x 40 = 24
Kemudian B+10, maka
; A+(B+10) = 50
A = 24/50 x 100% = 48%

9.1/6x12=2
10.60%x40 = 60/100x40=2400/100=24
60%x10=60/100x10=600/100=6
maaf kalau salah ya dek
