直接寫出得數(shù)． 2× 3 4 =	3 8 ×12=	9 16 ÷3=	3 10 ×5=	1 2 + 1 3 =
6 5 ÷ 1 3 =	5 12 ÷ 5 6 =	9 10 × 5 6 =	3 4 - 1 3 =	4 9 ÷ 1 2 =

Answer 1

考點：分數(shù)乘法,分數(shù)的加法和減法,分數(shù)除法

專題：計算題

分析：本題根據(jù)分數(shù)乘法、除法、加法及減法的運算法則計算即可．

解答： 解：

2× 3 4 = 3 2	3 8 ×12= 9 2	9 16 ÷3= 3 16	3 10 ×5= 3 2	1 2 + 1 3 = 5 6
6 5 ÷ 1 3 = 18 5	5 12 ÷ 5 6 = 1 2	9 10 × 5 6 = 3 4	3 4 - 1 3 = 5 12	4 9 ÷ 1 2 = 8 9

點評：完成本題細心分析式中數(shù)據(jù)，注意通分及約分．
