$\frac {4}{15}=\frac {8}{30}，$$\frac {11}{30}=\frac {11}{30}$

$\frac {8}{30}＜\frac {11}{30}，$$\frac {4}{15}＜\frac {11}{30}$

$\frac {7}{12}=\frac {49}{84}，$$\frac {4}{7}=\frac {48}{84}$

$\frac {49}{84}>\frac {48}{84}，$$\frac {7}{12}>\frac {4}{7}$

$\frac {5}{6}=\frac {15}{18}，$$\frac {7}{9}=\frac {14}{18}$

$\frac {15}{18}>\frac {14}{18}，$$\frac {5}{6}>\frac {7}{9}$

$\frac {11}{8}=\frac {55}{40}，$$\frac {13}{10}=\frac {52}{40}$

$\frac {55}{40}>\frac {52}{40}，$$\frac {11}{8}>\frac {13}{10}$

$6÷7=\frac 67$

$9÷10=\frac {9}{10}$

$\frac 67＜\frac {9}{10}$

$15÷4=\frac {15}{4}$

$\frac {7}{9}=\frac {14}{18}，$$\frac {5}{6}=\frac {15}{18}$

$\frac {14}{18}<\frac {15}{18}，$$\frac {7}{9}<\frac {5}{6}$

答：文文答对的题数多。

$\frac {8}{15}=\frac {32}{60}，\frac {7}{10}=\frac {42}{60}，\frac {9}{20}=\frac {27}{60}$

$\frac {9}{20}＜\frac {8}{15}＜\frac {7}{10}$

$1$升包装的销售量$<300$毫升包装的销售量$<500$毫

升包装的销售量

答：我会多进500毫升包装的饮料，因为500毫

升包装的饮料销售量最多。

$\frac {2022}{2023}=1-\frac {1}{2023}，$$\frac {2023}{2024}=1-\frac {1}{2024}$

$\frac {1}{2023}＞\frac {1}{2024}，$则$1-\frac {1}{2023}＜1-\frac {1}{2024}$

所以$\frac {2022}{2023}＜\frac {2023}{2024}$。
