分析:(1)先算乘法,再算減法;
(2)運用乘法交換律與結合律簡算;
(3)運用乘法分配律簡算;
(4)先算括號內(nèi)的,再算括號外的乘法,最后算加法;
(5)把102看作100+2,運用乘法分配律簡算;
(6)把原式變?yōu)?.7×4+1.7×6+1.7×10,運用乘法分配律簡算.
解答:解:(1)14.6-4.6×2.8,
=14.6-12.88,
=1.72;
(2)12.5×0.4×2.5×8,
=(12.5×8)×(0.4×2.5),
=100×1,
=100;
(3)4.2×1.25+4.8×1.25-1.25,
=(4.2+4.8-1)×1.25,
=8×1.25,
=10;
(4)5.96+13×(3.2-3.12),
=5.96+13×0.08,
=5.96+1.04,
=7;
(5)13.5×102,
=13.5×(100+2),
=1350+27,
=1377;
(6)0.17×40+0.017×600+1.7×10,
=1.7×4+1.7×6+1.7×10,
=1.7×(4+6+10),
=1.7×20,
=34.
點評:此題考查了小數(shù)的四則混合運算,注意運算順序和運算法則,靈活運用所學的運算律簡便計算.
