Question

Пожалуйста помогите ​

Answer 1

$\frac{2}{9}+\frac{5}{6}=\frac{4}{18}+\frac{15}{18}=\frac{19}{18}=1\frac{1}{18}$

$\frac{5}{12}-\frac{4}{15}=\frac{25}{60}-\frac{16}{60}=\frac{9}{60}=\frac{3}{20}=0,15$

$4\frac{5}{7}+2\frac{3}{8}=\frac{33}{7}+\frac{19}{8}=\frac{264}{56}+\frac{133}{56}=\frac{397}{56}=7\frac{5}{56}$

$5\frac{2}{15}-3\frac{7}{18}=\frac{77}{15}-\frac{61}{18}=\frac{462}{90}-\frac{366}{90}=\frac{96}{90}=1\frac{6}{90}=1\frac{2}{30}=1\frac{1}{15}$
