0.125x7.2的简便方法

0.125*8*0.9=0.9

0.125*7.2= 0.125*8*0.9=0.9

0.125*7.2=0.125*8*0.9=1*0.9=0.9

=0.125x8x0.9=1x0.9=0.9

可以看做分数1/8*72/10=9/10=0.9

原式=0.125*8*0.9=1*0.9=0.9

1.25x7.2用简便方法计算=1.25x8x0.9=10x0.9=9

0.25*0.125*7.2=0.25*0.125*0.8*9=0.25*0.125*0.8*9=0.25*0.1*9=0.025*10-1=0.025*10-0.025*1=0.25-0.025=0.225

0.125乘七点二简便计算解:0.125乘七点二=0.125*8*0.9=1*0.9=0.9
