Solution Steps

Step 1: Convert 30 deciseconds to seconds

To convert deciseconds (ds) to seconds (s), we use the conversion factor: \[ 1 \, \text{ds} = 0.1 \, \text{s} \] Thus, \[ 30 \, \text{ds} = 30 \times 0.1 \, \text{s} = 3 \, \text{s} \]

Step 2: Convert 4000 meters to kilometers

To convert meters (m) to kilometers (km), we use the conversion factor: \[ 1 \, \text{km} = 1000 \, \text{m} \] Thus, \[ 4000 \, \text{m} = \frac{4000}{1000} \, \text{km} = 4 \, \text{km} \]

Step 3: Convert 700 centiliters to liters

To convert centiliters (cL) to liters (L), we use the conversion factor: \[ 1 \, \text{cL} = 0.01 \, \text{L} \] Thus, \[ 700 \, \text{cL} = 700 \times 0.01 \, \text{L} = 7 \, \text{L} \]

Final Answer

The completed table is: \[ \begin{tabular}{|rr|} \hline $30 \, \text{ds} =$ & $\boxed{3 \, \text{s}}$ \\ \hline $\boxed{4 \, \text{km}} =$ & 4000 \, \text{m} \\ \hline $700 \, \text{cL} =$ & $\boxed{7 \, \text{L}}$ \\ \hline$\square \, \text{Mg} =$ & 5000000 \, \text{g} \\ \hline \end{tabular} \]
