脱式计算,能简算的要简算

脱式计算能简算的要简算是什么意思 意思是:脱式计算,能简算的要简算是什么意思 1、先观察算式有无简算的可能 2、如果有简算,那就用简算来做;没有,就直接计算

0.375*3/5+2/5*3/8+2÷3/8 =3/8*3/5+2/5*3/8+2*8/3 =3/8*(3/5+2/5)16/3 =3/8*1+16/3 =3/8+16/3 =9/24+128/24 =137/24 =5又17/24

(382X26分之7+0.618X26分之7)X3又7分之5 =(382*7/26+0.618*7/26)*26/7 =382+0.618 =382.618 5分之4+25分之3X21分之5+5分之3X2 =4/5+3/25*5/21+3/5*2 =4/5+1/35+6/5 =28/35+1/35+42/35 =71/35 333X332332332-332X333333333 =333X333333333-333*...

请采纳

3.6×1.02 =3.6×1+3.6×0.02 =3.6+0.072 =3.672 乘法分配率

①0.75×4×0.25×4, =0.75×(4×0.25)×4, =0.75×1×4, =3 ②9.6+9.9×99, =9.6+980.1, =989.7; ③15.58÷8.2-0.72, =1.9-0.72, =1.18 ④4.536÷0.8÷14, =5.67÷14, =0.405 ⑤2.8×3.6+1.4×2.8, =(3.6+1.4)×2.8, =5×2.8, =14 ⑥6.3×10.1, =6.3×...

12.5x(100+8)=12.5x12.5=156.25

4.82-13.5+9.18 =4.82+9.18-13.5 =14-13.5 =0.5 =3.8*(15.6-5.6) =3.8*10 =38 =4÷2 =2 =15.4÷【0.8*17.5】 =15.4÷14 =1.1

应该是不得分,能简算的必须简算,这是考察一能不能看出简算,而不是结果对不对的问题

=99x110+110 =110x(99+1) =110x100 =11000
