Răspuns:

Explicație pas cu pas:

·$\frac{1}{3} +\frac{2}{5} *\frac{7}{4} -\frac{5}{6} =\\ \frac{1}{3}+\frac{7}{10}-\frac{5}{6} =$

aducem la acelasi numitor (60)

$\frac{1}{3}+\frac{7}{10}-\frac{5}{6} =\\ \frac{20}{60}+\frac{42}{60}-\frac{50}{60}=\\\\ \frac{20+42-50}{6-} =\\ \frac{12}{60} =\\ \frac{2}{10} =\\ \frac{1}{5}$
