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(jù)0乘任何數(shù)都得0來(lái)計(jì)算；運(yùn)用加法交換律簡(jiǎn)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(jiǎn)算；其它混合運(yùn)算的題目按照運(yùn)算順序直接計(jì)算．
點(diǎn)評(píng)：本題是基本的計(jì)算題目，計(jì)算時(shí)要細(xì)心，注意把結(jié)果化成最簡(jiǎn)分?jǐn)?shù)．
