第1题 (22944-22.944)/(45888-45.888) =(22.944*(1000-1))/(45.888*(1000-1))=22.944/45.888=1/2
第2题:
(1+1.2)+(2+1.2*2)+(3+1.2*3)+...+(99+1.2*99)+(100+1.2*100)
=1+1.2+2+1.2*2+3+1.2*3+.+99+1.2*99+100+1.2*100
=1+2+3+.+99+100+1.2*(1+2+3+.+99+100)
=2.2*(1+2+3+.+99+100)

1 (22944-22.944)/(45888-45.888) =(22.944*(1000-1))/(45.888*(1000-1))=22.944/45.888=0.5
2 (1+1.2)+(2+1.2*2)+(3+1.2*3)+...+(99+1.2*99)+(100+1.2*100)=1.3*1+1.3*2+1.3*3+……+1.3*99+1.3*100=1.3*(1+2+3+……+99+100)=1.3*((1+100)+(2+99)+(3+98)+……+(50+51))=1.3*(101*50)=1.3*5050=6565
(22944-22.944)%(45888-45.888)=[22944(1-0.01)]/[45888(1-0.01)]=2
(1+1.2)+(2+1.2*2)+(3+1.2*3)+...+(99+1.2*99)+(100+1.2*100)=(1+2+3+...+99+100)(1+1.2)=5050*2.2=11110
(22944-22.944)/(45888-45.888) =(22.944*(1000-1))/(45.888*(1000-1))=22.944/45.888=0.5
(1+1.2)+(2+1.2*2)+(3+1.2*3)+...+(99+1.2*99)+(100+1.2*100)
