Answer 1

Explicação passo a passo:

a) $\frac{4}{5} . \frac{2}{3} = \frac{8}{15}$

b) $\frac{6}{3} . \frac{2}{4} = \frac{12}{12}$ simplificando =1

c) $\frac{12}{3} : \frac{4}{5} = \frac{12}{3} . \frac{5}{4} = \frac{60}{12}$ simplificando =5

d) $\frac{4}{3} : \frac{6}{2} = \frac{4}{3} . \frac{2}{6} = \frac{8}{18}$ simplificando = $\frac{4}{9}$

e) $\frac{2}{3} - \frac{1}{3} = \frac{2-1}{3} = \frac{1}{3}$

f) $\frac{4}{8} + \frac{12}{8} = \frac{4+12}{8} = \frac{16}{8}$ simplificando =2

g) MMC de 3 e 6 = 6, então: $\frac{2}{3} - \frac{3}{6} = \frac{2-3}{6} = \frac{-1}{6}$

h) MMC de 8 e 6 = 24, então: $\frac{4}{8} + \frac{2}{6} =\frac{4+2}{24} = \frac{8}{24}$ simplificando =$\frac{1}{3}$
