简便计算4.3一4.3x0.9

4.3减4.3乘0.9=4.3x(1-0.9)=4.3x0.1=0.43

4.6*1.25+5/4*4.3-0.9*125%-1 =(4.6+4.3-0.9)*1.25-1=8*1.25-1=10-1=9

5.4x4.3+4.3x4.3=(5.4+4.3)x4.3=(10-0.2)x4.3=10x4.3-0.2x4.3=43-0.86=42.14 行家正解,不明白可以追问!祝您学习进步 满意请点击下面的【选为满意回答】按钮,O(∩_∩)O谢谢

=4.3+(5.5*1-5.5*0.1)=4.3+(5.5-0.55)=4.3+4.95=9.25

4.3*0.9+4.3*0.9=4.3*0.9*2=3.87*2=7.74

简便计算4.3x4.9十4.3x5十4.3=4.3x(4.9+5+1)=4.3x10.9=43+4.3x0.9=43+4.3-0.43=46.87

4.3x9+4.3=4.3*(9+1)=4.3*10=43

展开全部4.3x1.o2=4.3*(1+0.02)=4.3*1+4.3*0.02=4.3+0.086=7.386

4.3x4.3-4.3x2.3=4.3*(4.3-2.3)=4.3*2=8.6

4.3*0.9=4.3-0.43=3.87
