Answer 1

a) $\frac{3}{5} + \frac{2}{3} . \frac{1}{5} = \frac{3}{5} + \frac{2}{15} = \frac{9}{15} + \frac{2}{15} = \frac{11}{15} *mmc 5, 15 = 15$

b) $\frac{3}{4} . \frac{5}{6} + \frac{1}{2} = \frac{15}{20} + \frac{1}{2} = \frac{15}{20} + \frac{10}{20} = \frac{25}{20}$

simplifique por 5


\frac{5}{4}

*mmc de 20, 2 = 20
