$\begin {aligned}&\frac {13}{14}=\frac {65}{70}，\frac {7}{10}=\frac {49}{70}\\&\frac {65}{70}>\frac {49}{70}，\frac {13}{14}>\frac {7}{10}\end {aligned}$

答：$\frac {1}{4}$ > $\frac {1}{5}$，乙跑得快。

答： $\frac {7}{4}$ > $\frac {8}{5}$，甲的跳远成绩好。

甲杯糖的含量：$\frac {40}{40+60}$=$\frac {2}{5}$

乙杯糖的含量：$\frac {50}{50+70}$=$\frac {5}{12}$

$\frac {2}{5}$ < $\frac {5}{12}$

答：乙杯甜。

答：往乙杯中加5克水。

$\frac {2022}{2023}$比$1$少$\frac {1}{2023}$

$\frac {2023}{2024}$比1少 $\frac {1}{2024}$

因为 $\frac {1}{2023}$ > $\frac {1}{2024}$，

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