Question

知識圣誕樹：直接寫出得數(shù)．

9 16 × 4 9 =	4 3 ÷ 2 3 =	5 14 ÷ 5 7 =	3 4 ÷ 15 16 =
10÷ 1 5 =	3 4 × 8 15 =	7 8 × 1 7 ÷ 1 2 =	9 10 ÷ 1 2 × 1 3 =

Answer 1

分析：本題根據分數(shù)乘法與除法的運算法則計算即可．

解答：解：

9 16 × 4 9 = 1 4	4 3 ÷ 2 3 =2	5 14 ÷ 5 7 = 1 2	3 4 ÷ 15 16 = 4 5
10÷ 1 5 =50	3 4 × 8 15 = 2 5	7 8 × 1 7 ÷ 1 2 = 1 4	9 10 ÷ 1 2 × 1 3 = 3 5

點評：完成分數(shù)乘法與除法算式要細心，注意約分．
