Question

3 8 ×4=	7 18 × 9 77 =	13 18 ×1=	27× 16 81 =
1 5 × 1 4 =	1 8 ×6=	1 2 + 1 4 =	5 12 × 3 5 =
5 6 × 9 10 =	13 29 ×0=	3 4 × 2 3 =	2 5 × 2 3 =

Answer 1

分析：分数乘法：分子相乘的积做分子，分母相乘的积做分母，能约分的先约分．

解答：解：

3 8 ×4= 3 2	7 18 × 9 77 = 1 22	13 18 ×1= 13 18	27× 16 81 = 16 3
1 5 × 1 4 = 1 20	1 8 ×6= 3 4	1 2 + 1 4 = 3 4	5 12 × 3 5 = 1 4
5 6 × 9 10 = 3 4	13 29 ×0=0	3 4 × 2 3 = 1 2	2 5 × 2 3 = 4 15 ．

点评：本题考查了分数乘法的计算，计算时要细心，注意把结果化成最简分数．
