2.4×0.35×1.6的简便计算

Answer 1

2.4×0.35×1.6的简便计算

原式=0.6*4*0.35*1.6
=0.6*1.4*1.6
=0.84*1.6
=1.344

1.6-0.35+4.94简便计算

1.6-0.35+4.94
=1.6+4.94-0.35
=1.6+4.59
=6.19
----------------------------------

2.4乘1.6—32乘0.12简便计算

2.4×1.6-32×0.12
=2.4×1.6-1.6×20×0.12
=2.4×1.6-1.6×2.4
=0

2.4+1.6×0.9-2.19简便计算

整数放一起算，小数放一起算
=2.4+1.6x(1-0.1)-(2+0.2-0.01)
=2.4+1.6-0.16-2-0.2+0.01
=4-2-0.2-0.16+0.01
=2-0.2-0.15
=2-0.35
=1.65

(0.35+0.7)0.35简便计算

(0.35+0.7)0.35简便计算
(0.35+0.7)+0.35
=0.35+0.35+0.7
=0.7+0.7
=1.4

53.6除以1.6乘2.4简便计算

53.6／1.6*2.4
=53.6*（2.4／1.6）
=53.6*1.5
=53.6*（1+0.5）
=53.6+53.6*0.5
=53.6+26.8
=80.4

(3.8十1.6x2)?0.35简便计算(3.8十1.6X2)0.35

简便计算
(3.8十1.6X2)÷0.35
=（3.8+3.2）÷0.35
=7÷0.35
=20

0.35×12简便计算

0.35×12
=0.35x2x6
=0.7x6
=4.2
