10.5乘0.75減0.5乘0.75的简便方法计算

10.5×0.75-0.5×0.75 =(10.5-0.5)×0.75 =10×0.75 =7.5

0.5X0.5X10X20 =10X20÷2÷2 =10X5 =50

无解 65%+10乘0.5 =65%+10×0.5 =0.65+5 =5.65

0.038×5×0.6 =0.038×(5×0.6) =0.038×3 =0.114 10.5×8.3+10.5×1.7 =10.5×(8.3+1.7) =10.5×10 =105 102×0.5 =(100+2)×0.5 =100×0.5+2×0.5 =50+1 =51 3.29×99+3.29 =3.29×(99+1) =3.29×100 =329 0.72×98 =0.72×(100-2) =0.72×100-0.72×2 =72-1.44 =...

建议直接计算,没有相加得到整数,或者相乘得到整十数,或者提取公因数的简便方法。 4.05×0.5+10.75 =2.025+10.75 =12.775

10-0.75 0.25/0.5简便计算 10-0.75 0.25/0.5 =10-0.75+0.5 =9.25+0.5 =9.75

1)6.8*15*0.5=1.7*2*2*15*0.5=1.7*(2*15)*(2*0.5)=1.7*30*1=51 2)6.8*15*0.5=6.8*0.5*15=3.4*15=3.4*(10+5)=3.4*10+3.4*5=34+17=51 如何进行简便计算 在进行简便计算之前,要求学生对所学的性质、定律、规律等有透彻的理解和正确的使用。也就...

12.5×7.8×0.8 =12.5×0.8×7.8 =10×7.8 =78

10.4加9.6乘0.5简便方法计算 10.4加9.6乘0.5 =10.4+4.8 =15.2 直接计算

(0.75+1/6)÷11/10÷0.4×5/8 =11/12×10/11÷0.4×5/8 =5/6×5/2×5/8 =125/96 你好,本题已解答,如果满意 请点右下角“采纳答案”。
