1 2 ÷4=	1 2 × 3 4 =	2÷ 4 3 =
4 7 ÷ 6 7 =	8 7 ×5=	1 3 - 1 5 =
7 15 ÷ 1 10 =	5 6 ÷ 1 4 =	4 5 - 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、與減法的運算法則計算即可．

解答： 解：

2 3 × 2 5 = 4 15	1 2 ÷ 3 5 = 5 6	4 3 - 1 4 = 13 12
1 2 ÷4= 1 8	1 2 × 3 4 = 3 8	2÷ 4 3 = 3 2
4 7 ÷ 6 7 = 2 3	8 7 ×5= 40 7	1 3 - 1 5 = 2 15
7 15 ÷ 1 10 = 14 3	5 6 ÷ 1 4 = 10 3	4 5 - 1 2 = 3 10

點評：完成本題要細心分析式中數(shù)據(jù)，在保證做題質量的同時，注意提高做題的速度．
