Answer 1

这道题可以这样简算：
1.25×4.8×0.25
=1.25×8×0.6×0.25
=10×0.6×0.25
=6×0.25
=1.5

Answer 2

1.25×4.8×0.25
=(1.25×8)×(0.6×0.25)
=10X0.15
=1.5

Answer 3

1.25×4.8×0.25
=1.25×(0.8×3×2)×0.25
=(1.25×0.8)×3×(2×0.25)
=1×3×0.5
=1.5

Answer 4

利用乘法结合律进行简便
=1.25×8×0.6×0.25
=（1.25×8）×（0.6×0.25）
=10×0.015
=0.15

Answer 5

4.8拆分成8和0.6
1.25×4.8×0.25
＝(1.25×8)×(0.6×0.25)
＝10×0.15
＝1.5
