Question

18．下列分?jǐn)?shù)中$\frac{1}{3}$，$\frac{3}{4}$，$\frac{6}{6}$，$\frac{4}{2}$，$\frac{13}{10}$，$\frac{5}{7}$，真分?jǐn)?shù)有$\frac{1}{3}$、$\frac{3}{4}$、$\frac{13}{10}$、$\frac{5}{7}$，假分?jǐn)?shù)有$\frac{6}{6}$、$\frac{4}{2}$．

Answer 1

分析 真分?jǐn)?shù)的分子小于分母，假分?jǐn)?shù)的分子大于或等于分母．

解答 解：下列分?jǐn)?shù)中$\frac{1}{3}$，$\frac{3}{4}$，$\frac{6}{6}$，$\frac{4}{2}$，$\frac{13}{10}$，$\frac{5}{7}$，
真分?jǐn)?shù)有 $\frac{1}{3}$、$\frac{3}{4}$、$\frac{13}{10}$、$\frac{5}{7}$，
假分?jǐn)?shù)有 $\frac{6}{6}$、$\frac{4}{2}$．
故答案為：$\frac{1}{3}$、$\frac{3}{4}$、$\frac{13}{10}$、$\frac{5}{7}$，$\frac{6}{6}$、$\frac{4}{2}$．

點(diǎn)評(píng) 此題主要考查真分?jǐn)?shù)、假分?jǐn)?shù)的分類，關(guān)鍵是根據(jù)分子分母的關(guān)系解答．
