Question

va rog
5/6 + 7/3 -2 intregi 3/4

Answer 1

$\frac{5}{6} + \frac{7}{3} - 2 \frac{3}{4} =$
$\frac{5}{6} + \frac{7}{3} - \frac{11}{4 } =$
$\frac{5}{6} amplificat \: cu \: 2 = \frac{10}{12}$
$\frac{7}{3} amplificat \: cu \: 4 = \frac{28}{12}$
$\frac{11}{4} \: amplificat \: cu \: 3 = \frac{33}{12}$
$\frac{10}{12} + \frac{28}{12} - \frac{33}{12} = \frac{5}{12}$
