Answer 1

Răspuns:

$a)3 \frac{1}{5} \times \frac{5}{14} + \frac{5}{6} = \frac{16}{5} \times \frac{5}{14} = \frac{8}{7} + \frac{5}{6} = \frac{48}{42} + \frac{30}{42} = \frac{78}{42} =1 \frac{36}{42}$

$c)1 \frac{19}{36} - 3 \frac{5}{14} \times \frac{7}{9} = \frac{47}{14} \times \frac{7}{9} = \frac{47}{9} =5 \frac{2}{9}$

Mult succes!!!!!
