Question

5.7×4.4+5.7×5.6的简便计算

Answer 1

5.7×4.4+5.7×5.6的简便计算

5.7×4.4+5.7×5.6
=5.7×（4.4+5.6）
=5.7×10
=57

简便计算4.9×5.6+5.7+5.6

4.9x5.6+5.7x5.6
=（4.9+5.7）x5.6
=10.6x5.6
=10x5.6+0.6x5.6
=56+3.36
=59.36

用简便计算0.1+0.2+0.3......+5.6+5.7

0.1+0.2+0.3......+5.6+5.7
=(0.1+5.7)+(0.2+5.6)+……+(2.8+3.0)+2.9
=5.8+5.8+……+5.8+2.9
=5.8×28+2.9
=165.3

简便计算 5.7×2.5×0.4×0.6 5.6×2.8＋13.32

5.7×2.5×0.4×0.6
=5.7×(2.5×0.4)×0.6
=5.7×1×0.6
=4.32
5.6×2.8＋13.32
= 5.6×(3-0.2)＋13.32
=16.8-1.12+13.32
=16.8+12.2
=29

5.7+4.3-5.7+4.3简便计算。

=(5.7 - 5.7) + (4.3 + 4.3)
=0 + 8.6
=8.6

5.7+0.1-5.7-0.1简便计算

5.7+0.1-5.7-0.1
=5.7-5.7+0.1-0.1
=0+0
=0

简便计算5.7x9.5÷5.7

5.7x9.5÷5.7
=5.7÷5.7x9.5
=1x9.5
=9.5

5.7乘13.7+6.3乘5.7简便计算

5.7×（13.7+6.3）
=5.7×20
=114

5.7X99+5.7的简便计算

5.7X(99+1)
=5.7*100
=570

6.3 5.7÷0.3简便计算

(6.3+5.7)/0.3
=12/0.3
=40
