Question

c. 2 intregi 5/7-(1/3)+5=​

Answer 1

Răspuns:

$= \frac{169}{21}$

Explicație pas cu pas:

$2 \frac{5}{7} - \Big( - \frac{1}{3} \Big) + 5$

$= \frac{2 \times 7 + 5}{7} + \frac{1}{3} + \frac{5}{1}$

$= \frac{ {}^{3)} 19}{7} + \frac{ {}^{7)} 1}{3} + \frac{{}^{21)} 5}{1}$

$= \frac{57}{21} + \frac{7}{21} + \frac{105}{21} = \frac{57 + 7 + 105}{21} = \boxed{\frac{169}{21} }$
