①11.23-3.4+8.77-6.6 =11.23+8.77-(3.4+6.6) =20-10 =10; ②5.4÷[0.68÷(1.2-1.03)] =5.4÷[0.68÷0.17] =5.4÷4 =1.35; ③(3.24×99+3.24)÷8.1 =[3.24×(99+1)]÷8.1 =324÷8.1 =40; ④(18.4-3.75)÷12.5÷0.8 =14.65÷12.5÷0.8 =14.65÷(12.5×0.8) =14.65÷10 =1.465; ⑤12.6÷[(4.3-4.12)×35] =12.6÷[0.18×35] =12.6÷6.3 =2; ⑥15.76÷4-3.76×0.25 =15.76×1 4 -3.76×1 4 =(15.76-3.76)×1 4 =12×1 4 =3.
