-(3)/(2)abc+(5)/(3)ab-(3)/(4)bc+(2)/(5)abc-(4)/(5)ab+(1)/(2)bc=

Para simplificar la expresión dada, primero combinamos términos semejantes:<br /><br />$-\frac{3}{2}abc + \frac{2}{5}abc = -\frac{15}{10}abc + \frac{4}{10}abc = -\frac{11}{10}abc$<br /><br />$\frac{5}{3}ab - \frac{4}{5}ab = \frac{25}{15}ab - \frac{12}{15}ab = \frac{13}{15}ab$<br /><br />$-\frac{3}{4}bc + \frac{1}{2}bc = -\frac{6}{8}bc + \frac{4}{8}bc = -\frac{2}{8}bc = -\frac{1}{4}bc$<br /><br />Por lo tanto, la expresión simplificada es:<br /><br />$-\frac{11}{10}abc + \frac{13}{15}ab - \frac{1}{4}bc$
