126*5+5*74 =(126+74)*5 =200*5 =1000

40x74x5 =74x(40x5) =74x200 =14800 先算40乘以5就简单一些

解:25×28 =25×(4×7) =25×4×7 =(25×4)×7 =100×7 =700 解:75×4 =3×25×4 =3×(25×4) =3×100 =300

490除以7加24乘5简便运算 490÷7+24x5 =70+120 =190 祝学习进步。

75乘74分之5 =(74+1)乘74分之5 =5+74分之5 =5又74分之5

4.6x5.7+23 =2.3x11.4+2.3x10 =2.3x(11.4+10) =2.3x21.4 =49.22

原式=25分之7×7分之5+25分之7×4分之25 =5分之1+4分之7 =20分之4+20分之35 =20分之39

2.74*9.5+5*0.274 =2.74*9.5+2.74*0.5 =2.74*(9.5+0.5) =2.74*10 =27.4
