Answer 1

考点：整数的加法和减法,分数的加法和减法,分数乘法,分数除法,小数乘法,小数除法

专题：运算顺序及法则

分析：根据加减乘除四则运算的口算方法进行求解即可．

解答： 解：

369+31=400	1000-218=782	0.7×40=28	7.14÷7=1.02	7.14+0.86=8
0.45÷0.9=0.5	1÷ 1 8 =8	1 3 - 1 4 = 1 12	0.375+ 5 8 =1	8 13 × 7 8 = 7 13
1 5 9 + 7 18 =1 17 18	6- 2 3 =5 1 3	5 1 3 -5= 1 3	0.6× 5 6 =0.5	1.2÷ 3 4 =1.6
0×7 3 8 =0	0.9÷0.01=90	1 7 - 1 9 = 2 63

点评：本题属于基本的计算，在平时都积累经验，逐步提高运算的速度和准确性．
