$\bf 1.\\ \\ \it a)\ \ 0,4(2)=0,422...;\ \ \dfrac{3}{7}=0,428...;\ \dfrac{48}{16}=3\\ \\ \\ -3 < -0,9 < 0 < 0,4(2) < \dfrac{3}{7} < \dfrac{48}{16}\\ \\ \\ b) \ \ \ F;\ \ A;\ \ A;\ \ A.$

$\bf2.\\ \\ \it a)\ \ \dfrac{30}{100}\cdot120=\dfrac{3600}{100}=36\\ \\ \\ b)\ \ \dfrac{^{30)}0,6}{\ \ 4}=\dfrac{18}{x} \Rightarrow \dfrac{18}{120}=\dfrac{18}{x} \Rightarrow x=120$
