Answer 1

考点：分数除法,分数的加法和减法,分数乘法,分数的四则混合运算

专题：运算顺序及法则

分析：运用分数、小数的四则运算的计算法则进行计算即可．

解答：

解：6÷ 3 4 =8	8 9 ÷ 9 8 = 64 81	1 2 + 2 5 = 9 10	3-1.95=1.05
0× 5 11 =0	9-2 2 3 =6 1 3	0.8×2.4=1.92	5 6 - 1 2 = 1 3     1 2 + 1 4 + 1 8 = 7 8
4- 5 8 =3 3 8	9÷ 27 29 =9 2 3	3 1 9 ×18=56	3.75+1 1 4 =5
2 2 3 ÷4= 2 3	9.625- 5 8 =9	1 3 5 ×1.5=2.4	3 4 × 2 5 ÷ 3 4 × 2 5 = 4 25
（1-1.2÷1 1 3 ）÷ 1 5 = 1 2

点评：考查了四则运算，关键是熟练掌握计算法则正确进行计算．
