Số học sinh giỏi là: 40 : 5 = 8 (học sinh)
Số học sinh trung bình là:
(40−8).38=12(40-8).38=12 (học sinh)
Số học sinh khá là: 40 - 8 - 12 = 20 (học sinh)
b) Tỉ số % học sinh giỏi là:
8:40=0,2=20%8:40=0,2=20%
Tỉ số % học sinh trung bình là:
12:40=0,3=30%12:40=0,3=30%
Tỉ số % học sinh khá là:
100%−20%−30%= 50%

\(3,2,1,0,00,000,0000,...\)
\(\text{So, 00 = -1, 000 = -2 and 0000 = -3. and it follows that 000 + 0000 = -2 + (-3) = -5}\)
ko co so nao khac 0 ca kick minh nhe
