Answer 1

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；．
分析：，，根據0乘任何數都得0來計算；運用加法交換律簡算；，3.4--根據連續減去兩個數等于減去這兩個數的和簡算；其它混合運算的題目按照運算順序直接計算．
點評：本題是基本的計算題目，計算時要細心，注意把結果化成最簡分數．
