(2 2/3 + 1 5/6): 1 1/2 по действиям.: Математика

$2\frac{2}{3} + 1\frac{5}{6}: \frac{11}{2}= \frac{9}{11}$
1) $2\frac{2}{3} + 1\frac{5}{6} = \frac{8}{3} + \frac{11}{6} = \frac{8*2}{6} + \frac{11}{6}= \frac{16+11}{6} = \frac{27}{6}$
2) $\frac{27}{6} : \frac{11}{2}= \frac{27}{6} * \frac{2}{11}= \frac{27*2}{6*11} = \frac{27}{3*11}= \frac{9}{11}$
