Răspuns:

Explicație pas cu pas:

$\it{ \frac{14 {}^{(2} }{30} - \frac{6}{15} + \frac{4 {}^{(4} }{12} = \frac{7}{15} - \frac{6}{15} + \frac{1}{3} = \frac{1}{15} + \frac{ {}^{5)} 1}{3} = \frac{1}{15} + \frac{5}{15} = \frac{6 {}^{(3} }{15} = \frac{2}{5} }$

Answer 2

$\frac{14}{30} - \frac{6}{15} + \frac{4}{12} =$

$\frac{28}{60} - \frac{24}{60} + \frac{20}{60} = \frac{4}{60} + \frac{20}{60} = \frac{1}{15} + \frac{1}{3} = \frac{1}{15} + \frac{5}{15} = \frac{6}{15} = 0.4$
