您好:4.4x0.25=4x0.25x1.1=1x1.1=1.1 如果本题有什么不明白可以追问,如果满意请点击“采纳为满意回答” 如果有其他问题请采纳本题后另发点击向我求助,答题不易,请谅解,谢谢.祝学习进步!

4.4x0.25=4+0.4*0.25=4*0.25+0.4*0.25=1+0.1=1.1

4.4x0.25=1.1*(4*0.25)=1.1*1=1.1

4.4*0.25=(1.1*4)*0.25=1.1*(4*0.25)=1.1*1=1.1

4*0.25=1 0.4*0.25=0.11+0.1=1.1

4*0.25+0.4*0.25=1.1

4.4x0.25=(4+0.4)x0.25=4x0.25+0.4x0.25=1+0.1=1.1

4.4x0.25x6=1.1x4x0.25x6=1.1x(4x0.25)x6=1.1x1x6=6.6

0.8*6.25-4.4*0.25=0.8*(6+0.25)-(4+0.4)*0.25=(0.8*6+0.8*0.25)-(4*0.25+0.4*0.25)=[4.8+0.2*(4*0.25)]-(1+0.1)=(4.8+0.2*1)-1.1=4.8+0.2-1.1=5-1.1=3.9

4.4=44/100.25=1/44.4*0.25=44/10*1/4=11/10=1.1
