\[\boxed{\text{6.142.}}\]

\[\textbf{а)}\ 12 \cdot 8 = 96;\ \]

\[96 + 14 = 110;\ \]

\[110\ :11 = 10;\ \]

\[10 \cdot 15 = 150;\ \]

\[150\ :25 = 6.\ \]

\[\textbf{б)}\ 16 \cdot 3 = 48;\ \]

\[48\ :12 = 4;\ \]

\[4 \cdot 13 = 52;\ \]

\[52 + 38 = 90;\ \]

\[90\ :18 = 5.\ \]

\[\textbf{в)}\ 204\ :2 = 102;\ \]

\[102 \cdot 6 = 612;\ \]

\[612 + 8 = 620;\ \]

\[620\ :20 = 31;\ \]

\[31 - 19 = 12.\ \]

\[\textbf{г)}\ 320 - 12 = 308;\ \]

\[308\ :4 = 77;\ \]

\[77 + 123 = 200;\ \]

\[200 \cdot 8 = 1\ 600.\ \]

\[\textbf{д)}\ 350 + 250 = 600;\ \]

\[600\ :20 = 30;\ \]

\[30 + 273 = 303;\ \]

\[303\ :3 = 101.\ \ \ \]
