\[\boxed{\text{6.44.}}\]

\[\textbf{а)}\ 450 \cdot 2 = 900;\ \]

\[900 - 250 = 650;\ \]

\[650\ :13 = 50;\ \]

\[50 \cdot 7 = 350.\ \]

\[\textbf{б)}\ 364 + 116 = 480;\ \]

\[480\ :6 = 80;\ \]

\[80 + 70 = 150;\ \]

\[150 \cdot 8 = 1\ 200.\ \]

\[\textbf{в)}\ 200 \cdot 5 = 1\ 000;\ \]

\[1\ 000 - 250 = 750;\ \]

\[750\ :150 = 5;\ \]

\[5 \cdot 12 = 60.\ \]

\[\textbf{г)}\ 480\ :20 = 24;\ \]

\[24 + 80 = 104;\ \]

\[104\ :4 = 26;\ \]

\[26 \cdot 20 = 520.\ \]

\[\textbf{д)}\ 300 - 40 = 260;\ \]

\[260\ :13 = 20;\ \]

\[20 \cdot 10 = 200;\ \]

\[200\ :20 = 10.\ \ \ \]
