Answer 1

[Đặng Viết Thái]

\(\frac{14}{15}-\frac{5}{6}=\frac{1}{10}\)

\(\frac{9}{7}-\frac{9}{14}=\frac{9}{14}\)

\(2-\frac{3}{4}=\frac{5}{4}\)

Answer 2

[_Shadow_]

\(\frac{14}{15}-\frac{5}{6}=\frac{28}{30}-\frac{25}{30}=\frac{3}{30}=\frac{1}{10}\)

\(\frac{9}{7}-\frac{9}{14}=\frac{18}{14}-\frac{9}{14}=\frac{9}{14}\)

\(2-\frac{3}{4}=\frac{8}{4}-\frac{3}{4}=\frac{5}{4}\)
