1. Выполните сложение:
- \( 24 + (-6) = 24 - 6 = 18 \)
- \( 2 \frac{1}{6} + (-3 \frac{2}{3}) = \frac{13}{6} - \frac{11}{3} = \frac{13}{6} - \frac{22}{6} = \frac{13 - 22}{6} = \frac{-9}{6} = -1 \frac{3}{6} = -1 \frac{1}{2} \)
- \( -\frac{2}{9} + \frac{14}{11} = \frac{-2 \cdot 11 + 14 \cdot 9}{99} = \frac{-22 + 126}{99} = \frac{104}{99} = 1 \frac{5}{99} \)
Ответ: а) 18; б) -1 1/2; в) 1 5/99.
