2.1 3.5 0.2的简便计算

2.1/3.5/0.4的简便运算2.1÷3.5÷0.4 =2.1÷(3.5x0.4)=2.1÷1.4=1.5 希望能帮到你

(2.1+2.1/0.21)/0.2如何简便计算=(2.1+10)/0.2=12.1/0.2=60.5

(4.2-4.2/2.1)/0.2=(4.2-2)/0.2=2.2/0.2=22/2=11

2.1*3.5+2.1*2.5用简便的方法计算=2.1x(3.5+2.5)=2.1x6=12.6

2.1÷0.2=21÷2=10.5

0.2*4*3.5=0.2x3.5x4=0.7x4=2.8.你好,本题已解答,如果满意 请点右下角“采纳答案”.

1/5/[(2/3+0.2)*1/26]= 1/5 / [(2/3+1/5)*1/26]= 1/5 /(13/15*1/26)= 1/5 / (1/30)= 1/5 * 30= 6

原式=1.8*3.5+3.5*0.2 =(1.8+0.2)*3.5 =2*3.5 =7

你好!解:500X3.5X0.2=(500X0.2)X3.5=100X3.5=350 仅代表个人观点,不喜勿喷,谢谢.

能2.1÷3.5÷0.4=0.3*7÷7÷(0.5*0.4)=0.3÷0.2=1.5
