Question

直接寫出得數(shù)． 3 2 × 2 3 =	0÷ 11 18 =	3 4 × 1 6 =	8 5 ÷8=
2 11 ×22=	5 16 ÷ 3 4 =	9 7 × 14 3 =	5 9 ÷ 15 9 =

Answer 1

分析：分?jǐn)?shù)乘整數(shù)，用分?jǐn)?shù)的分子和整數(shù)相乘的積做分子，分母不變；分?jǐn)?shù)乘分?jǐn)?shù)，用分子相乘的積做分子，分母相乘的積做分母，能約分的要約分；分?jǐn)?shù)除以一個(gè)數(shù)（0除外），等于乘這個(gè)數(shù)的倒數(shù)；據(jù)此解答即可．

解答：解：

3 2 × 2 3 =1	0÷ 11 18 =0	3 4 × 1 6 = 1 8	8 5 ÷8= 1 5
2 11 ×22=4	5 16 ÷ 3 4 = 5 12	9 7 × 14 3 =6	5 9 ÷ 15 9 = 1 3

點(diǎn)評(píng)：此題主要考查分?jǐn)?shù)乘除法的運(yùn)算法則的靈活應(yīng)用．
