Answer 2

1.25×5.6×2.5×4.4简便计算？
解:原式=1.25×(8×0.7)×2.5×4.4
=1.25×8×2.5×(4+0.4)×0.7
=10×2.5×(4+0.4)×0.7
=(25×4+25×0.4)×0.7
=(100+10)×0.7
=100×0.7+10×0.7
=70+7
=77

Answer 3

1.25×5.6×2.5×4.4
=1.25×8*0.7×2.5×4*1.1
=10*0.7*10*1.1
=7*11
=77

Answer 4

1.25×5.6×2.5×4.4怎么简便？
用乘法结合律计算即可。
1.25×5.6×2.5×4.4
=1.25x8x0.7x2.5x4x1.1
=（1.25x8）x（0.7x1.1）x（2.5x4）
=10x0.77x10
=77

Answer 5

=1.25*8*0.7*2.5*4*1.1
=（1.25*8）*（2.5*4）*0.7*1.1
=10*10*0.77
=77
