Answer 1

Resposta:

$\Big( \frac{3}{2}-\frac{2}{5}\Big)-\Big( \frac{5}{4}-\frac{2}{3}\Big)=\Big( \frac{15}{10}-\frac{4}{10}\Big)-\Big( \frac{15}{12}-\frac{8}{12}\Big)=\Big( \frac{15-4}{10}\Big)-\Big( \frac{15-8}{12}\Big)\\\\= \frac{11}{10}- \frac{7}{12}=\frac{66}{60}- \frac{35}{60}=\frac{66-35}{60}= \frac{31}{60}$
