Вычислите: 3/4 − 1/16; 2/3 − 1/18; 3/14 + 1/7; 4/5 − 2/15; 1/2 − 3/8; 7/15 + 1/3; 5/18 − 1/9; 3/4 + 5/12; 11/12 − 2/3; 6/17 − 3/34.

Приводим дроби к общему знаменателю, затем выполняем действие с числителями.

1. \(\frac{3}{4}-\frac{1}{16}=\frac{12}{16}-\frac{1}{16}=\frac{11}{16}\).
2. \(\frac{2}{3}-\frac{1}{18}=\frac{12}{18}-\frac{1}{18}=\frac{11}{18}\).
3. \(\frac{3}{14}+\frac{1}{7}=\frac{3}{14}+\frac{2}{14}=\frac{5}{14}\).
4. \(\frac{4}{5}-\frac{2}{15}=\frac{12}{15}-\frac{2}{15}=\frac{2}{3}\).
5. \(\frac{1}{2}-\frac{3}{8}=\frac{4}{8}-\frac{3}{8}=\frac{1}{8}\).
6. \(\frac{7}{15}+\frac{1}{3}=\frac{7}{15}+\frac{5}{15}=\frac{4}{5}\).
7. \(\frac{5}{18}-\frac{1}{9}=\frac{5}{18}-\frac{2}{18}=\frac{1}{6}\).
8. \(\frac{3}{4}+\frac{5}{12}=\frac{9}{12}+\frac{5}{12}=\frac{7}{6}\).
9. \(\frac{11}{12}-\frac{2}{3}=\frac{11}{12}-\frac{8}{12}=\frac{1}{4}\).
10. \(\frac{6}{17}-\frac{3}{34}=\frac{12}{34}-\frac{3}{34}=\frac{9}{34}\).
