脱式计算,能简算的要简算

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*...

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

是的,还要注意运算顺序,加减,乘除,以及括号等

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×...

如图

125+125X79 =125X(1+79) =125X80 =10000 9000÷125÷8 =9000÷(125X8) =9000÷1000 =9

望采纳

11/12×25-11/12 =11/12×(25-1) =11/12×24 =22
