Answer 1

考點(diǎn)：分?jǐn)?shù)乘法

專題：運(yùn)算順序及法則

分析：根據(jù)四則運(yùn)算的計算法則計算即可求解．

解答： 解：

1 2 × 1 2 = 1 4	3 11 × 2 3 = 2 11	4 5 × 5 8 = 1 2	4× 1 5 = 4 5
4 9 × 3 4 = 1 3	6 7 × 5 12 = 5 14	1 2 × 2 7 = 1 7	28× 4 35 = 16 5
7 8 - 3 4 = 1 8	3 5 ×0=0	5 6 × 2 3 = 5 9	5 9 × 4 7 = 20 63
24× 1 6 =4	1 3 × 3 7 = 1 7	7 8 × 2 3 = 7 12	55× 4 11 =20

點(diǎn)評：考查了四則運(yùn)算，關(guān)鍵是熟練掌握計算法則，正確進(jìn)行計算．
