Вычислите значение выражения, используя свойства сложения.
1) $\frac{7}{18} + \frac{11}{24} + \frac{5}{18} + \frac{13}{24} = (\frac{7}{18} + \frac{5}{18}) + (\frac{}{} + \frac{}{}) = $
2) $\frac{11}{50} + \frac{8}{15} + \frac{2}{15} + \frac{14}{50} = $
3) $1\frac{3}{32} + 3\frac{7}{72} + 2\frac{5}{32} + 4\frac{1}{36} = $
$\frac{7}{18} + \frac{11}{24} + \frac{5}{18} + \frac{13}{24} = (\frac{7}{18} + \frac{5}{18}) + (\frac{11}{24} + \frac{13}{24}) = \frac{12}{18} + \frac{24}{24} = \frac{2}{3} + 1 = 1\frac{2}{3}$
$\frac{11}{50} + \frac{8}{15} + \frac{2}{15} + \frac{14}{50} = (\frac{11}{50} + \frac{14}{50}) + (\frac{8}{15} + \frac{2}{15}) = \frac{25}{50} + \frac{10}{15} = \frac{1}{2}^{/3} + \frac{2}{3}^{/2} = \frac{3}{6} + \frac{4}{6} = \frac{7}{6} = 1\frac{1}{6}$
$1\frac{3}{32} + 3\frac{7}{72} + 2\frac{5}{32} + 4\frac{1}{36} = (1\frac{3}{32} + 2\frac{5}{32}) + (3\frac{7}{72} + 4\frac{1}{36}^{/2}) = 3\frac{8}{32} + (3\frac{7}{72} + 4\frac{2}{72}) = 3\frac{1}{4} + 7\frac{9}{72} = 3\frac{1}{4}^{/2} + 7\frac{1}{8} = 3\frac{2}{8} + 7\frac{1}{8} = 10\frac{3}{8}$
