3/2-7/3+5/3=

7/5+2/3-1/2=

Answer 1

$\frac{3}{2} - \frac{7}{3} + \frac{5}{3} = \frac{27}{18} - \frac{42}{18} + \frac{30}{18} = \frac{15}{18}$

$\frac{15}{18} ambas \: divididas \: por \: 3 = \frac{5}{6}$

$\frac{7}{5} + \frac{2}{3} - \frac{1}{2} = \frac{42}{30} + \frac{20}{30} - \frac{15}{30} = \frac{47}{30}$
