Question

小動(dòng)物過(guò)河去拜年 4 15 ÷ 12 13 =	21 50 ÷ 3 4 =	10 21 ÷ 4 35 =	21 32 ÷ 7 16 =
2 3 ÷ 4 7 =	12÷ 4 5 =	34 35 ÷ 13 28 =	1÷ 2 5 =

Answer 1

分析：根據(jù)分?jǐn)?shù)除法的計(jì)算法則：甲數(shù)除以乙數(shù)（0除外），等于甲數(shù)乘乙數(shù)的倒數(shù)；據(jù)此依次解答即可．

解答：

解： 4 15 ÷ 12 13 = 13 45	21 50 ÷ 3 4 = 14 25	10 21 ÷ 4 35 =4 1 6	21 32 ÷ 7 16 =1 1 2
2 3 ÷ 4 7 =1 1 6	12÷ 4 5 =15	34 35 ÷ 13 28 =2 6 65	1÷ 2 5 =2 1 2

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