考點(diǎn)：分?jǐn)?shù)的加法和減法,分?jǐn)?shù)乘法,分?jǐn)?shù)除法

專題：計算題

分析：按照分?jǐn)?shù)四則計算的計算法則直接計算得出答案即可．

解答：

解： 1 3 + 5 6 = 7 6	4 5 - 3 4 = 1 20	8 9 ×4= 32 9	7 8 ×0=0	5 3 × 3 10 = 1 2
1 3 - 5 24 = 1 8	8 9 ÷4= 2 9	5 9 ÷ 2 3 = 5 6	9÷ 1 8 =72	42× 5 14 =15

點(diǎn)評：掌握四則計算的計算法則是解決問題的關(guān)鍵，注意結(jié)果的化簡．
