0.125 9.8 8简便计算

解:依题意得算式,0.125*3.89*8=0.125*8*3.89=1*3.89=3.89102*1.25=(100+2)*1.25=100*1.25+2*1.25=125+2.5=127.59.8*3.56+5.44*9.8=9.8*(3.56+5.44)=(10-0.2)*9=10*9-0.2*9=90-1.8=88.2

0.125*8.8=0.125*(8+0.8)=0.125*8+0.125*0.8=1+0.1=1.1

9÷0.125=(9*8)÷(0.125*8)=72÷1=72你好,本题已解答,如果满意,请点右上角“采纳答案”,支持一下.

9除以0.125怎么简便计算9÷0.125=(9*8)÷(0.125*8)=72÷1=72

你好:0.125=1/80.125x8=1/8x8=1你好:0.125x8=(0.1+0.02+0.005)x8=0.1x8+0.02x8+0.005x8=0.8+0.16+0.04=1

0.125X2.8X8用简便方法列出算式=0.125X8X2.8(用乘法交换定律)=1X2.8=2.8

0.125x8.8=0.125x8x1.1=1x1.1=1.1

0.125=1/8 所以9 ÷0.125 =9 ÷(1/8) =9*8 =72

0.12588简便计算=0.125x8x11=1x11=110.125x88=0.125x(80+8)=0.125x80+0.125x8=10+1=11

①0.125*9*8*0.3,=(0.125*8)*(9*8),=1*72,=72;②4.62÷5÷0.66,=4.62÷(5*0.66),=4.62÷3.3,=1.4;③5.78*2.3+5.78+5.78*6.7,=5.78*(2.3+1+6.7),=5.78*10,=57.8;④7.75*[20÷(3.24-3.04)],=7.75*[20÷0.2],=7.75*100,=775.
