0.273 0.35解方程

0.273/X=0.35可得出X=0.273/0.35=0.78

解:0.273/x=0.35两边同乘以x得0.273/x*x=0.35*x 即0.35x=0.273两边同除以0.35得0.35x÷0.35=0.273÷0.35 x=0.78

0.273÷2x=0.352x=0.273÷0.35x=0.273÷0.35÷2x=0.78÷2x=0.39

①0.273÷x=0.35 0.273*1 x *x=0.35*x 0.35x=0.273 0.35x÷0.35=0.273÷0.35 x=273 350 ; ②x*1.6=0.8641.6x÷1.6=0.864÷1.6 x=0.54 ③x*3.6=0.864 3.6x=0.8643.6x÷3.6=0.864÷3.6 x=0.24; ④x÷0.756=90 x÷756 1000 =90x*1000 756 *756 1000 =90*756 1000 x=68.04;

X=0.273÷0.35=0.78

0.273÷x=0.35X=0.273÷0.35X=0.78xX1.6=0.864X=0.864÷1.6X=0.54xX3.6=0.864X=0.864÷3.6X=0.24x÷0.756=90X=90*0.756X=68.04

解:列式:0.273/0.35=0.78

解:0.273 + x = 0.35 273/1000 + x = 35/100 273/1000 + x = 350/1000 x = 350/1000 - 273/1000 x = 77/1000 ∴x = 0.077∴此方程的解为x = 0.077

0.273十*=0.35x=0.35-0.273x=0.077

(1)6x-3x=18;3x=18;x=6;(2)1.5x+18=3x ;1.5x=18;x=12;(3)5*3-x/2=8;x/2=15-8=7;x=7*2=14;
