列竖式计算70.8%0.8x0.5

直接计算即可: =70.8-0.4 =70.4

(1)2.8×7.6+1.4×2.8+2.8=2.8×(7.6+1.4+1)=2.8×10=28;(2)70.8-0.8×0.5=70.8-0.4=70.4;(3)13-3.79-6.21=13-(3.79+6.21)=13-10=3;(4)5×(40+0.7)=5×40+5×0.7=200+3.5=203.5;(5)4.12-1.78-1.22=4.12-(1.78+1.22)=4.12-3=1.12;...

公式如下: =if(G1

(1)12.5×(0.7×0.8),=12.5×0.8×0.7,=10×0.7,=7;(2)70.8-0.8×0.5,=70.8-0.4,=70.4;(3)13-3.79+6.21,=9.21+6.21,=15.42;(4)12.5×(40+0.7),=12.5×8×5+12.5×0.7,=500+8.75,=508.75;(5)4.12-1.78-1.22,=4.12-(1.78+1.2...

八分之一(x加0.5)等于百分之七十五 1/8(x+0.5)=0.75 x+0.5=0.75*8 x+0.5=6 x=5.5

解:70.9x1.08一0.8x7.08 =70.9x(1+0.08)一0.8x7.08 =70.9+70.9x0.08-70.8x0.08 =70.9+(70.9-70.8)x0.08 =70.9+0.1x0.08 =70.9+0.008 =70.908

7.08×2.7+70.8×0.73 =7.08x2.7+7.08x7.3 =7.08x(2.7+7.3) =7.08x10 =70.8

70÷(1-80%) =70÷20% =350(元)
