【答案】1.1，4，；4，，0，6，，；6，0，；，64，；，3，；，6，4；0，2，；，，86；3，，；2，2.4，；9.45，，100.1；0.9，1，81；．

【解析】

試題分析：，，根據(jù)0乘任何數(shù)都得0來計(jì)算；運(yùn)用加法交換律簡算；，3.4﹣﹣根據(jù)連續(xù)減去兩個(gè)數(shù)等于減去這兩個(gè)數(shù)的和簡算；其它混合運(yùn)算的題目按照運(yùn)算順序直接計(jì)算．

解：﹣2.7=1.1， 14×=4， ÷5=，

1=4， =， =0，

=6， ﹣=， =，

=6， =0， =，

=， 24=64， =，

=， =3， =，

=， =6， =4，

=0， =2， =，

=， =， =86，

=3， =， =，

0.25×8=2， 3.4﹣﹣=2.4， +0.5=，

10.5﹣1.05=9.45， =， 10.01÷10%=100.1，

1.5×=0.9， 80%=1， 1×9=81，

3×=．

故答案為：1.1，4，；4，，0，6，，；6，0，；，64，；，3，；，6，4；0，2，；，，86；3，，；2，2.4，；9.45，，100.1；0.9，1，81；．
