用分子3做比的前項(xiàng),分母5做比的后項(xiàng)可化成3:5;
3
5
的分子3做被除數(shù),分母5做除數(shù)可轉(zhuǎn)化成除法算式為3÷5,根據(jù)商不變的性質(zhì),被除數(shù)和除數(shù)同時(shí)乘3化成9÷15;0.6的小數(shù)點(diǎn)向右移動(dòng)兩位,同時(shí)添上百分號(hào)可化成60%;由此進(jìn)行轉(zhuǎn)化并填空.
解答:解:0.6=3:5=9÷15=60%.
故答案為:3,5,9,60.
點(diǎn)評(píng):此題考查小數(shù)、分?jǐn)?shù)、比、除法和百分?jǐn)?shù)之間的關(guān)系和轉(zhuǎn)化,也考查了分?jǐn)?shù)的性質(zhì)和商不變性質(zhì)的運(yùn)用.
