Question

(1/6+7/15)-2/15= пж прошу !!!@@​

Answer 1

Ответ:

1/6+7/15=5/30+14/30=19/30

19/30-2/15=19/30-4/30=15/30=1/2

Answer 2

$\frac{1}{6} + \frac{7}{15} = \frac{5}{30} + \frac{14}{30} = \frac{19}{30} \\ \frac{19}{30} - \frac{2}{15} = \frac{19}{30} - \frac{4}{30} = \frac{15}{30} = \frac{1}{2}$
