题目内容
3.2÷0.08=
320
320
÷8 1.92÷0.06
0.06
=1920÷60.分析:商不变的性质:在除法里,被除数和除数同时扩大或缩小相同的倍数(0除外),商不变;据此解答.
解答:解:3.2÷0.08,
=(3.2×100)÷(0.08×100),
=320÷8;
1920÷60,
=(1920÷1000)÷(60÷1000),
=1.92÷0.06;
故答案为:320,0.06.
=(3.2×100)÷(0.08×100),
=320÷8;
1920÷60,
=(1920÷1000)÷(60÷1000),
=1.92÷0.06;
故答案为:320,0.06.
点评:此题考查商不变性质的运用:只有被除数和除数同时扩大或缩小相同的倍数(0除外),商才不变.
