分析:①先算除法,再算減法;
②將32寫(xiě)成4與8的乘積,再運(yùn)用乘法結(jié)合律進(jìn)行計(jì)算;
③將8.8寫(xiě)成8與0.8的和,再運(yùn)用乘法分配律計(jì)算;
④將除以4轉(zhuǎn)換成乘0.25,再運(yùn)用乘法分配律計(jì)算;
⑤先計(jì)算小括號(hào)里的,再計(jì)算中括號(hào)里的,最后計(jì)算括號(hào)外面的.
解答:解:①36.8-6.8÷0.5,
=36.8-13.6,
=23.2;
②0.125×32×0.25,
=(0.125×8)×(4×0.25),
=1×1,
=1;
③1.25×8.8,
=1.25×(8+0.8),
=1.25×8+1.25×0.8,
=10+1,
=11;
④73÷4+2.7×0.25,
=73×
+2.7×0.25,
=(73+2.7)×0.25,
=75.7×0.25,
=18.925;
⑤3.75÷[0.3×(1.34-0.84)],
=3.75÷[0.3×0.5],
=3.75÷0.15,
=25.
