1.25×8.2(脱式计算)

你好!1.25*8.2(脱式计算)1.25*8.2 =1.25x(8+0.2)=1.25x8+1.25x0.2=10+0.25=10.25 希望能帮到你 仅代表个人观点,不喜勿喷,谢谢.

1.25*8.2(脱式计算)1.25*8.2=1.25*8+1.25*0.2=10+0.25=10.25

1.25*8点八=12.5*8*1.1=100*1.1=110

1.25*8.8脱式计算 解:根据拆分法和结合律的简便方法,原式=1.25x8x1.1=10x1.1=11

(1)1.25*3.69*8,=(1.25*8)*3.69,=10*3.69,=36.9;(2)32.4÷2.5÷0.4=32.4÷(2.5*0.4),=32.4÷1,=32.4;(3)8.3-2.76*1.5,=8.3-4.14,=4.16;(4)47.88÷6.3*8.2,=7.6*8.2,=62.32.

=1.25x(8+0.8)=1.25x8+1.25x0.8=10+1=11自己算一算哦..记得给我好评哦..

(1)0.08*720*1.25=0.08*1.25*720=0.1*720=72;(2)5.25*8.2+5.25*0.8+5.25=5.25*(8.2+0.8+1)=5.25*10=52.5;(3)0.125*808=0.125*(8*101)=(0.125*8)*101=1*101=101;(4)18.45-(3.8*2.7+5.3)=18.45-(10.26+5.3)=18.45-15.56=2.89;(5)0.5+7.2÷1.44*0.4=0.5+5*0.4=0.5+2=2.5;(6)1.32*(0.9÷18)=1.32*0.05=0.066.

1.25乘8.8的脱式计算=1.25*8+1.25*0.8=10+1=11

你好!1.25x1.3x8脱式计算1.25*1.3*8=1.25*8*1.3=10*1.3=13,请采纳,谢谢.记得给问豆啊!
