Answer 1

考點：小數(shù)除法,小數(shù)乘法

專題：運算順序及法則

分析：根據(jù)小數(shù)、整數(shù)四則運算的口算方法進行解答即可．

解答： 解：

6.3÷0.021=300	1.5÷0.03=50	0.43×5=2.15	0.7×8-0.6=5
72÷24=3	5×0.7=3.5	6.8+8.6=15.4	9.4×0.2=1.88
1.8÷0.9×0.5=1	580-400=180	43×0.01﹦0.43	3.72×0.2=0.744
99+0.1﹦99.1	3.2-2=1.2	6×0.125×8=6	630÷3=210
1.9×4﹦7.6	8.8÷0.11=80	4×1.2×0.25=1.2	560÷40=14

點評：本題考查了基本的小數(shù)、整數(shù)的四則運算法則，計算時要細心，注意小數(shù)點的位置．
