Помогите решить: 11/10 - 3/5 + 11/15

Answer 1

$\frac{11}{10} - \frac{3}{5} + \frac{11}{15} = \frac{13}{15} \\ 1) \frac{11}{10} - \frac{3}{5} = \frac{11}{10} - \frac{6}{10} = \frac{5}{10 } = \frac{1}{2} \\ 2) \frac{1}{2 } + \frac{11}{15} = \frac{15}{30} + \frac{11}{30} = \frac{26}{30} = \frac{13}{15}$
