三点7×0点125 6点三除以八简便计算

3.7×0.125 =(4-0.3)×0.125 =0.5-0.0375 =0.4625 6.3÷8 =(6.4-0.1)÷8 =6.4÷8-0.1÷8 =0.8-0.125 =0.675

12.5x6.3+27x1.25+0.125÷0.01 =1.25x63+27x1.25+0.125x100 =1.25x63+27x1.25+1.25x10 =1.25x(63+27+10) =1.25x100 =125

简便计算 9.8×8.5 =10×8.5-0.2×8.5 =85-1.7 =83.3 4.63×3.8+3.37×6.2 =1.26×3.8+3.37×3.8+3.37×6.2 =4.788+3.37×(3.8+6.2) =4.788+3.37×10 =4.788+33.7 =38.488 0.125×13.7×0.4 =(0.125×0.4)×13.7 =0.05×13.7 =0.665

(6.9×0.125×1.75)÷(2.3×8分之1×4分之1) =6.9×8分之1×4分之5÷2.3÷8分之1÷4分之1 =6.9÷2.3×(8分之1÷8分之1)×(4分之5÷4分之1) =3×1×5 =15

七点6×0点125 2点四除以八怎么简便 7.6*0.125+2.4÷8 =7.6*0.125+2.4*0.125 =0.125*(7.6+2.4) =0.125*10 =1.25

125*0.176+36.1/0.8+12.5*2.63 =0.125*176+361/8+0.125*263 =176/8+361/8+263/8 =(176+361+263)/8 =(170+360+260+10)/8 =800/8 =100

48分之6=0点125=11比88=百分之12.5 0.125=1/8=12.5% 推算出48分之6=0.125 11比88=0.125

1/8×6点二五-0点125除以1/4-百分之十二点五的过程 1/8×6.25-0.125÷1/4-12.5% =1/8×6.25-0.125×4-12.5% =1/8×(6.25-4-1) =1/8×1.25 =5/32

解:原式=83x6.5+3.6x7x125x32x25 =83x6.5+(4x25)x(8x125)x7x3.6 =83x6.5+100x1000x7x3.6 =83x(6+0.5)+700x3600 =83x6+83x0.5+2520000 =2520000+498+41.5 =2520498+41.5 =2520539.5

这道题利用分数, 因为0.125=1/8, 所以是6.7÷1/8=6.7×8=53.6。
