Question

16．在$\frac{1}{2}$、$\frac{4}{5}$、$\frac{22}{11}$、$\frac{15}{15}$、$\frac{78}{12}$中，真分?jǐn)?shù)有$\frac{1}{2}$、$\frac{4}{5}$，能化成帶分?jǐn)?shù)的假分?jǐn)?shù)有$\frac{78}{12}$．

Answer 1

分析 根據(jù)真分?jǐn)?shù)的意義，分子小于分母的分?jǐn)?shù)是真分?jǐn)?shù)；根據(jù)假分?jǐn)?shù)的意義，分子大于或等于分母的分?jǐn)?shù)是假分?jǐn)?shù)；假分?jǐn)?shù)中分子大于分母的能化成帶分?jǐn)?shù)．

解答 解：在$\frac{1}{2}$、$\frac{4}{5}$、$\frac{22}{11}$、$\frac{15}{15}$、$\frac{78}{12}$中，真分?jǐn)?shù)有：$\frac{1}{2}$、$\frac{4}{5}$，能化成帶分?jǐn)?shù)的假分?jǐn)?shù)有：$\frac{78}{12}$．
故答案為：$\frac{1}{2}$、$\frac{4}{5}$，$\frac{78}{12}$．

點(diǎn)評 此題是考查真、假分?jǐn)?shù)的意義、帶分?jǐn)?shù)的意義、假分?jǐn)?shù)化帶分?jǐn)?shù)的方法等．
