简便计算6年级上册

Answer 1

32×125×25

=4×8×125×25

=（4×25）×（8×125）

=100×1000

=100000
9048÷26

=（2600+2600+2600+1248）÷26

=2600÷26+2600÷26+2600÷26+1248÷26

=100+100+100+48

=348

2881÷ 43

=（1290+1591）÷ 43

=1290÷43+1591÷43

=30+37 =67 3.2×42.3×3.75-12.5×0.423×16

=3.2×42.3×3.75-1.25×42.3×1.6

=42.3×(3.2×3.75-1.25×1.6)

=42.3×(4×0.8×3.75-1.25×4×0.4)

=42.3×(4×0.4×2×3.75-1.25×4×0.4)

=42.3×(4x0.4x7.5-1.25x4x0.4)

=42.3×[4×0.4×(7.5-1.25)]

=42.3×[4×0.4×6.25]

=42.3×(4×2.5)

=423
