Answer 1

考点：分数的加法和减法,分数乘法,分数除法

专题：运算顺序及法则

分析：根据分数四则运算的运算法则进行计算即可．

解答： 解：

2 7 ÷2= 1 7	15÷ 1 5 =75	3 4 ×32=24	1÷ 1 10 =10	9× 1 6 =1.5
0÷ 1 4 =0	3 5 × 1 18 = 1 30	4 5 ÷ 3 5 = 4 3	4 21 ÷ 2 3 = 2 7	5 7 ÷50= 1 70
1 8 ÷2= 1 16	2 5 ×25=10	1 6 + 1 2 = 2 3	18× 7 9 =14	3 10 ÷3=0.1
100÷ 5 6 =120	7 15 ÷14= 1 30	5 12 ÷ 4 3 = 5 16	1 3 - 1 7 = 4 21	2 5 ÷ 1 10 =4

点评：此题考查了分数四则运算的运算法则的运用．
