简介:
(8.1-5.4)÷3.6+85.7 =2.7÷3.6+85.7 =0.75+85.7 =86.45 2.9×1.4+2×0.16 =4.06+0.32 =4.38 4.8×5÷0.3 =24÷0.3 =80 102×0.45 =100×0.45+2×0.45 =45+0.9 =45.9 4.3×0.25×0.4 =4.3×(0.25×0.4) =4.3×0.1 =0.43 81×1.01 =81×(1+0.01) =81×1+81×0.01 =81+0.81=81.81 7.4+42.6÷7.1 =7.4+6 =13.4 5.6÷40×8.1 =0.14×8.1 =1.134 12-3.5-6.3-2÷10 =12-3.5-6.3-0.2 =12-(3.5+6.3+0.2) =12-10
