算一算． 3 14 ×28=	2 15 ×25=	4× 1 5 =	3 8 × 2 9 =	27× 5 36 =
18× 2 3 =	0× 8 9 =	3 7 × 3 7 =	2 25 ×10=	5 14 × 2 5 =

Answer 1

分析：根據(jù)分?jǐn)?shù)乘分?jǐn)?shù)的計(jì)算法則及一個(gè)數(shù)乘分?jǐn)?shù)的計(jì)算法則，分別進(jìn)行解答即可．

解答：

解： 3 14 ×28=6	2 15 ×25= 10 3	4× 1 5 = 4 5	3 8 × 2 9 = 1 12	27× 5 36 = 15 4
18× 2 3 =12	0× 8 9 =0	3 7 × 3 7 = 9 49	2 25 ×10= 4 5	5 14 × 2 5 = 1 7 ．

點(diǎn)評(píng)：明確分?jǐn)?shù)法的計(jì)算法則，是解答此題的關(guān)鍵．
