分析:(1)(2)(3)根據(jù)四則運(yùn)算的計(jì)算法則進(jìn)行計(jì)算,
(4)根據(jù)乘法分配律進(jìn)行計(jì)算,
(5)根據(jù)一個(gè)數(shù)連續(xù)減兩個(gè)數(shù),等于減去這兩個(gè)數(shù)的和,進(jìn)行計(jì)算,
(6)根據(jù)乘法結(jié)合律進(jìn)行計(jì)算.
解答:解:(1)(0.32÷16+1.08)÷22,
=(0.02+1.08)÷22,
=1.1÷22,
=0.05;

點(diǎn)評:考查了運(yùn)算定律與簡便運(yùn)算,四則混合運(yùn)算.注意運(yùn)算順序和運(yùn)算法則,靈活運(yùn)用所學(xué)的運(yùn)算律簡便計(jì)算.
