3.64÷4+2.37x0.9
答案3.043，计算过程：3.64➗4+2.37x0.9 =0.91+2.37x（1-0.1） =0.91+2.37-2.37x0.1 =3.28-0.237 =3.043，拆分的方法0.9=1-0.1
答案3.043，计算过程：3.64➗4+2.37x0.9 =0.91+2.37x（1-0.1） =0.91+2.37-2.37x0.1 =3.28-0.237 =3.043，拆分的方法0.9=1-0.1
0.9=1-0.1，然后运用乘法分配律
3.64➗4=0.91
(9.28÷3.2+75)x4.9
(9.28÷3.2+75)x4.9 =（2.9+75）x4.9 =77.9x4.9 =381.71
18.9-18.9÷1.4+2.1
18.9-18.9÷1.4+2.1 =18.9-13.5+2.1 =（18.9+2.1）-13.5 =21-13.5 =7.5
