Question

直接写得数．

24× 2 3 =	11 14 × 7 33 =	7 25 × 5 14 =	0× 13 50 =
9 40 ×8=	7 3 × 5 7 =	9 16 × 4 15 =	42× 5 14 =

Answer 1

分析：分数乘法的计算法则：分子乘分子，分母乘分母，能约分的先约分．

解答：解：

24× 2 3 =16	11 14 × 7 33 = 1 6	7 25 × 5 14 = 1 10	0× 13 50 =0
9 40 ×8= 9 5	7 3 × 5 7 = 5 3	9 16 × 4 15 = 3 20	42× 5 14 =15

点评：本题考查简单的分数乘法的计算，计算时要细心，注意把结果化成最简分数．
