9.6*1.4+3.2*5.8=3.2*3*1.4+3.2*5.8=3.2*(3*1.4+5.8)=3.2*10=32再问:(9.45+9.9)÷0.9谢谢再答:(9.45+9.9)÷0.9=9.45
(1)(28.7-6)x0.8=22.7x0.8=18.16(2)0.72+3=3.72(3)69.3+14.7/2.1=69.3+7=76.3(4)3.4/(1.7x5)=2/5=0.4再问:都不要
0.38+9.6÷3.2.×5.4=0.38+3*5.4=0.38+16.2=16.5826.7-0.5×0.5-0.75=26.7-(0.25+0.75)=26.7-1=25.75.5×17.3+6
3.41×9.9×0.38÷(0.19×33/10×1.1)=3.41÷1.1X9.9÷3.3X0.38÷0.19=3.1X3X2=3.1X6=18.6
3.2×5.8÷0.16=3.2÷0.16×5.8=20×5.8=116
3.6÷9+9.6-3×0.3,=0.4+9.6-0.9,=10-0.9,=9.1.
9.6÷2.5×3÷4=(9.6×3)÷(2.5x4)=28.8÷10=2.88
1.6÷0.25+0.96÷3.2=1.6÷0.25+1.92÷1.6=1.6÷(0.25+0.96)3.2借2个0.96=1.6=1.6÷1.21
2.25*【9.6/3.2/2.5】=2.25/2.5*3=2.7
0.36+9.6÷3.2=0.36+3=3.36
先用9.6除以3.2再乘5.4+0.38
实在有点.=9.6/(0.1*3)/3.2----将第二项分开=9.6/0.1/3/3.2=9.6/0.1/9.6----将后两项合并=0.1
9.6×5.3÷4.8=9.6÷4.8×5.3=2x5.3=10.6
5+10+15+20+.+100这是等差数列,有20个数,可以利用高斯的算法:(5+100)*20=2100.0.38×7.6+0.38÷2.5+0.38×2=0.38×(7.6+1/2.5+2)=0
0.36+9.6/3.2=0.36+3=3.36
9.6÷3.2÷0.5=(9.6÷3.2)÷0.5=3÷0.5=66.71×0.52+4.8×6.71=6.71×(0.52+4.8)=6.71×5.32=35.6972PS:应该是0.48吧,那样的
0.38+9.6/0.32*5.4=0.38+30*5.4=0.38+162=162.38
