3) $y = \frac{1}{3}$

а) $y= \frac{1}{3} * (-18) = -6$

б)$y= \frac{1}{3} * 7 = \frac{7}{3} = 2\frac{1}{3}$

в)$y= \frac{1}{3} * 5.16 = \frac{1}{3} * \frac{129}{25} = \frac{43}{25} = 1\frac{18}{25} = 1.72$

г)$y= \frac{1}{3} * (-23.4) = \frac{1}{3} * (-\frac{117}{5} ) = -\frac{39}{5} = -7\frac{4}{5} = -7.8$

4)$y= -4\frac{3}{7}$

а)$y= -4\frac{3}{7} * 49 = -\frac{31}{7} * 49 = -31 * 7 = -217$

б)$y= -4\frac{3}{7} *(-2.8) = -\frac{31}{7} * \frac{14}{5} = -\frac{62}{5} = - 12\frac{2}{5} = -12.4$

в)$y= -4\frac{3}{7} * 0.07 = -\frac{31}{7} *\frac{7}{100} = - \frac{31}{100} = -0.31$

г)$y=-4\frac{3}{7} * 57.4 =-\frac{31}{7} *\frac{287}{5} = -\frac{1271}{5} = -254\frac{1}{5} = -254.2$
