分析:(1)利用加法交換律解答即可;
(2)利用連續(xù)減去兩個(gè)數(shù)等于減去這兩個(gè)數(shù)的和進(jìn)行簡(jiǎn)算;
(3)(4)(5)利用乘法分配律簡(jiǎn)算即可;
(6)按運(yùn)算順序解答即可.
解答:解:(1)4.32+5.43+6.68,
=4.32+6.68+5.43,
=11+5.43,
=16.43;
(2)17.17-6.8-3.2,
=17.17-(6.8+3.2),
=17.17-10,
=7.17;
(3)5.29×9+5.29,
=5.29×(9+1),
=5.29×10,
=52.9;
(4)16.8×10.1,
=16.8×10+16.8×0.1,
=168+1.68,
=169.68;
(5)2.74×9.5+5×0.274,
=2.74×9.5+0.5×2.74,
=2.74×(9.5+0.5),
=2.74×10,
=27.4;
(6)0.36+9.6÷3.2,
=0.36+3,
=3.36.
點(diǎn)評(píng):此題考查主要根據(jù)算式運(yùn)算符號(hào)和數(shù)字的特點(diǎn),靈活運(yùn)用運(yùn)算定律進(jìn)行簡(jiǎn)便計(jì)算.
