- \(\frac{55}{2}+\frac{33}{17}=\frac{1001}{34}\).
- \(\frac{10}{7}-\frac{15}{2}=\frac{-85}{14}\).
- \(\frac{8}{10}-\frac{7}{7}=\frac45-1=-\frac15\).
- \(15\frac{10}{3}-2\frac{12}{11}=\frac{55}{3}-\frac{34}{11}=\frac{503}{33}=15\frac{8}{33}\).
- \(\frac{12}{7}-\frac{50}{3}=\frac{-314}{21}\).
- \(\frac85+\frac{10}{3}=\frac{74}{15}=4\frac{14}{15}\).
- \(\frac31+\frac83=3+\frac83=5\frac23\).
- \(\frac15+\frac42=\frac15+2=2\frac15\).
- \(\frac23+\frac{12}{4}=\frac23+3=3\frac23\).
- \(\frac81+\frac{10}{3}=8+\frac{10}{3}=11\frac13\).
- \(\frac{10}{5}-0=2\).
- \(\frac{50}{10}+\frac82=5+4=9\).
- \(\frac15+\frac{58}{13}=\frac{303}{65}=4\frac{43}{65}\).
- \(\frac{13}{2}-\frac{36}{14}=\frac{13}{2}-\frac{18}{7}=\frac{55}{14}=3\frac{13}{14}\).
- \(\frac31+\frac{18}{2}=3+9=12\).
