分析:①⑤運用乘法的分配律進行計算即可.②運用乘法的結(jié)合律及交換律進行解答即可.③運用加法的結(jié)合律及一個數(shù)連續(xù)減去兩個數(shù),可以用這個數(shù)減去這兩個數(shù)的和進行解答即可.④按照小數(shù)的四則混合運算的順序進行計算即可.⑥運用一個數(shù)連續(xù)減去兩個數(shù),可以用這個數(shù)減去這兩個數(shù)的和進行解答即可
解答:解:①2.4×1.5+3.6×1.5,
=1.5×(2.4+3.6),
=1.5×6,
=9;
②0.125×2.5×8,
=(0.125×8)×2.5,
=1×2.5,
=2.5;
③7.38-5.14+3.62-2.86,
=(7.38+3.62)-(2.86+5.14),
=11-8,
=3;
④17.2-7.2×0.6,
=17.2-4.32,
=12.88;
⑤8.9×9.9,
=8.9×(10-0.1),
=8.9×10-8.9×0.1,
=89-0.89,
=88.11;
⑥41.9-2.08-7.92,
=41.9-(2.08+7.92),
=41.9-10,
=31.9.
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.
