Answer 2

$\it a)\ \ \dfrac{3}{5}\cdot4=0,6\cdot4=2,4;\ \ \ [2,4]=2,\ \ \ \{2,4\}=0,4}\\ \\ \\ b)\ \ 8\cdot\dfrac{2}{3}= \dfrac{16}{3}=5,(3);\ \ \ [5,(3)]=5,\ \ \{5,(3)\}=0,(3)\\ \\ \\ c)\ \ \dfrac{4}{7}\cdot3= \dfrac{12}{7}=1,(714285);\ \ \ [1,(714285)]=1,\ \ \{1,(714285)\}=0,(714285)$

$\it d)\ \ \dfrac{12}{25}\cdot5= \dfrac{3\cdot4\cdot5^{(5}}{25}= \dfrac{3\cdot4}{5}= \dfrac{3}{5}\cdot4\ \bigg(analog\ cu\ a)\bigg)$
