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

專題：計(jì)算題

分析：根據(jù)分?jǐn)?shù)乘法和分?jǐn)?shù)除法及分?jǐn)?shù)加減法的計(jì)算方法進(jìn)行計(jì)算．

解答：

解： 2 9 ×4= 8 9	5× 3 10 = 3 2	4 5 × 3 8 = 3 10	1 1 3 ×6=8	7 12 + 5 6 = 17 12
9 14 × 14 15 × 5 9 = 1 3	0÷ 8 9 × 7 18 =0	28 7 9 × 1 7 =4 1 9	5 4 9 ×0=0	17-7 4 8 =9 1 2
