1) \(\frac{5}{6}+\frac{3}{14}=\frac{5 \cdot 7 + 3 \cdot 3}{42}=\frac{35+9}{42}=\frac{44}{42}=\frac{22}{21}\)
2) \(1\frac{1}{8} \cdot \frac{22}{21}=\frac{9}{8} \cdot \frac{22}{21}=\frac{9 \cdot 22}{8 \cdot 21}=\frac{3 \cdot 11}{4 \cdot 7}=\frac{33}{28}=1 \frac{5}{28}\)
3) \(5 \frac{5}{16}-1 \frac{5}{28}=5 \frac{35}{112}-1 \frac{20}{112}=4\frac{15}{112}\)
Ответ: \(4\frac{15}{112}\)
