\[\boxed{\text{6.101.}}\]

\[\textbf{а)}\ 16 \cdot 4 = 64;\ \]

\[64 + 11 = 75;\ \]

\[75\ :15 = 5;\ \]

\[5 \cdot 17 = 85;\ \]

\[85 + 18 = 103.\ \]

\[\textbf{б)}\ 95\ :5 = 19;\ \]

\[19 + 56 = 75;\ \]

\[75\ :25 = 3;\ \]

\[3 \cdot 27 = 81;\ \]

\[81 + 29 = 110.\ \]

\[\textbf{в)}\ 38 \cdot 10 = 380;\ \]

\[380\ :19 = 20;\ \]

\[20 \cdot 50 = 1\ 000;\ \]

\[1\ 000 \cdot 3 = 3\ 000;\ \]

\[3\ 000 - 200 = 2\ 800.\ \]

\[\textbf{г)}\ 60\ :3 = 20;\ \]

\[20 \cdot 15 = 300;\ \]

\[300 + 280 = 580;\ \]

\[580\ :20 = 29;\ \]

\[29 - 14 = 15.\ \]

\[\textbf{д)}\ 200 - 12 = 188;\ \]

\[188\ :2 = 94;\ \]

\[94 - 56 = 38;\ \]

\[38 \cdot 3 = 114;\ \]

\[114 + 18 = 132.\ \ \ \]
