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×=．

故答案为：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：，，根据0乘任何数都得0来计算；运用加法交换律简算；，3.4--根据连续减去两个数等于减去这两个数的和简算；其它混合运算的题目按照运算顺序直接计算．
点评：本题是基本的计算题目，计算时要细心，注意把结果化成最简分数．
