205﹣199+95= 8.8+1.2= 8π≈ 0.33=

【答案】0.25,2,6,,0.36,0.5,,37,101,10,24,0.027.

【解析】

试题分析:(1)(2)(3)(4)(5)(6)依据分数四则运算计算方法解答,

(7)(8)(9)(10),依据整数和小数四则运算计算方法解答,

(11)把π看作3解答,

(12)依据求一个数的立方计算方法解答.

解:=0.25; =2; ×8=6; =

18×2%=0.36 1﹣=0.5; 3.5÷18=; 137﹣63﹣37=37;

205﹣199+95=101; 8.8+1.2=10; 8π≈24; 0.33=0.027.

故答案依次为:0.25,2,6,,0.36,0.5,,37,101,10,24,0.027.
