$$
\begin{array}{l|l|l|l}
6 \cdot 7 & 9 \cdot 0 & 26+17 \\
45: 5 & 73-19 & 6 \text{~cm}=\ldots \text{mm} & \begin{array}{l}
28: 4 \\
70 \text{dm}=\ldots \text{m}
\end{array}
\end{array}
$$
$6 \cdot 7=42, 9 \cdot 0=0, 26+17=43, 28: 4=7, 45: 5=9, 73-19=54, 6 \text{ cm}=60 \text{ mm}, 70 \text{ dm}=7 \text{ m}$
