解答:解:(1)18.76×9.9+1.876,
=18.76×9.9+18.76×0.1,
=18.76×(9.9+0.1),
=18.76×10,
=187.6;
(2)3.52÷2.5÷0.4,
=3.52÷(2.5×0.4),
=3.52÷1,
=3.52;
(3)3.65×10.1,
=3.65×(10+0.1),
=3.65×10+3.65×0.1,
=36.5+0.365,
=36.865;
(4)1.25×2.5×32,
=1.25×2.5×(4×8),
=(1.25×8)×(2.5×4),
=10×10,
=100;
(5)3.9-4.1+6.1-5.9,
=(3.9+6.1)-(4.1+5.9),
=10-10,
=0;
(6)3.75-(3.75+6.48),
=3.75-3.75-6.48,
=0-6.48,
=-6.48;
(7)15.6×13.1-15.6-15.6×2.1,
=15.6×(13.1-1-2.1),
=15.6×10,
=156;
(8)56.5×9.9+5.65,
=5.65×99+5.65,
=5.65×(99+1),
=5.65×100,
=565.
點評:完成本題要注意分析式中數(shù)據(jù),運用合適的簡便方法計算.
