13/58+21/58-m=6/29 4/5+2/3 5/6+7/9 3/4-1/6 7/8-5/6

Решите задачу:

$1) \frac{13}{58}+ \frac{21}{58} -m= \frac{6}{29} \\ \\ \frac{34}{58}-m= \frac{6}{29} \\ \\ \frac{17}{29}-m= \frac{6}{29} \\ \\ m= \frac{17}{29} - \frac{6}{29} \\ \\ m= \frac{11}{29}$

$2) \frac{4}{5} + \frac{2}{3} = \frac{12}{15} + \frac{10}{15} = \frac{22}{15} =1 \frac{7}{15} \\ \\ 3) \frac{5}{6} + \frac{7}{9}= \frac{30}{36}+ \frac{28}{36}= \frac{58}{36}=1 \frac{22}{36} =1 \frac{11}{18} \\ \\ 3) \frac{3}{4} - \frac{1}{6} = \frac{9}{12}- \frac{2}{12}= \frac{7}{12} \\ \\ 4) \frac{7}{8} - \frac{5}{6} = \frac{21}{24}- \frac{20}{24}= \frac{1}{24}$
