6.8+0.1%6.8+0.1怎样脱式计算

8.9×0.1+0.1×1 =0.1×(8.9+0.1) =0.1×9 =0.9

(8.1÷0.4+0.5)×0.6 =(8÷0.4+0.1÷0.4+0.5)×0.6 =(20+0.25+0.5)×0.6 =20×0.6+0.25×0.6+0.5×0.6 =12+0.15+0.3 =12.45

21.6÷0.8-1.2x5 =27-6 =21

1.68÷0.8+1.52 = 2.1+1.52 =3.62

32·8x1·5÷0·6 =16.4X2X1.5÷0·6 =16.4X3÷0·6 =16.4X5 =82

(19.9-0.1)÷0.2+1=100 0.1+0.3+0.5+0.7+0.9+1.1···19.7+19.9 =(0.1+19.9)X100÷2 =1000

3.5×[(1-0.05)×0.6] =3.5x(1x0.6-0.05x0.6) =3.5x(0.6-0.03) =3.5x0.6-3.5x0.03 =2.1-0.105 =1.995

=2.4×0.19+2.4×0.81 =2.4×(0.19+0.81) =2.4×1 =2.4

1-0.1×1/10+10%÷0.1 =1-0.1×0.1+0.1÷0.1 =1-0.01+1 =1.99

1.84÷(1.84÷0.5) =1.84÷1.84x0.5 =1x0.5 =0.5 希望帮到你 望采纳 谢谢 加油
