解：（1）25×4×3.2
=100×3.2
=320；???????????（2）32×3.2×0.7
=102.4×0.7
=71.68；?????????（3）4.4×0.4×0.4
=1.76×0.4，
=0.704；（4）2×0.7×3.3
=1.4×3.3
=4.62；?????????????????????????????（5）0.125×32×2.5
=0.125×（8×4）×2.5
=（0.125×8）×（4×2.5）
=1×10
=10．
解析分析：（1）（2）（3）（4）按运算顺序从左往右依次计算；（5）将0.125×32×2.5变形为0.125×（8×4）×2.5，再根据乘法结合律简便计算．
点评：此题考查了数的脱式计算，特别注意运算顺序和运算法则，以及运算律的灵活运用．
