Ответ:
\(\frac{1}{10}+\frac{1}{5}=\frac{3}{10}\).
\(\frac{3}{15}-\frac{2}{4}=\frac{1}{5}-\frac{1}{2}=-\frac{3}{10}\).
Ответ: \(\frac{1}{10}+\frac{1}{5}>\frac{3}{15}-\frac{2}{4}\).
\(\frac{1}{10}+\frac{1}{5}=\frac{3}{10}\).
\(\frac{3}{15}-\frac{2}{4}=\frac{1}{5}-\frac{1}{2}=-\frac{3}{10}\).
Ответ: \(\frac{1}{10}+\frac{1}{5}>\frac{3}{15}-\frac{2}{4}\).
