(4.6-3.2)×11.5的脱式计算

Answer 1

(4.6-3.2)×11.5的脱式计算

(4.6-3.2)×11.5
=1.4*11.5
=(1+0.4)*11.5
=1*11.5+0.4*11.5
=11.5+4.6=16.1

用简便方法计算0.38x101(4.6-3.2)x11.5

用简便方法计算0.38x101(4.6-3.2)x11.5
0.38x101
=0.38*100+0.38
=38+0.38
=38.38
(4.6-3.2)x11.5
=1.4*11.5
=16.1

(4.6-3.2)乘以11.5用简便方法咋算

解:(4.6-3.2)*11.5
=1.4*11.5
=(1+0.4)*(10+1.5)
=10+1.5+4+0.6
=16.1

9.06 18.2÷(4.6-3.2)的简便运算

9.06 +18.2÷(4.6-3.2)
=9.06+18.2÷1.4
=9.06+13
=22.06

6.38 4.6-6.38 4.6脱式计算

6.38+4.6-6.38+4.6
=（6.38-6.38）+（4.6+4.6）
=0+9.2
=9.2

125×3.2 脱式计算

125×3.2
=125×3-125×0.2
=375-25
=350

(2.8 3.85÷3.5)×4.6脱式计算

(2.8 3.85÷3.5)×4.6脱式计算
(2.8 3.85÷3.5)×4.6
=（2.8+1.1）*4.6
=3.9*4.6
=17.94

2.8×4.6-3.68脱式计算

2.8×4.6-3.68脱式计算
2.8×4.6-3.68
=12.88-3.68
=9.2
直接计算

4.6-1.75+2.08脱式计算

4.6-1.75+2.08脱式计算
4.6-1.75+2.08
=2.85+2.08
=4.93.

4.6×1.05减2.8脱式计算

4.6 x 1.05 - 2.8
= 4.6 x (1 + 0.05) - 2.8
= 4.6 x 1 + 4.6 x 0.05 - 2.8
= 4.6 + 0.23 - 2.8
= 2.03
