Metric Prefixes are “labels” that can be placed in front of base units. Whenever using the metric prefix chart, remember that “1” is associated with the metric prefix. 

Conversion factors needed:

1 km (kilometer) = 10³ m (meters)
1 dm (decimeter) = 10^-1 m (meters)

1 cm (centimeter) = 10^-2 m (meters)

km to dm: 

$\mathbf{515}\mathbf{ }\cancel{\mathbf{km}}\mathbf{\times }\frac{{\mathbf{10}}^{\mathbf{3}}\mathbf{ }\cancel{\mathbf{m}}}{\mathbf{1}\mathbf{ }\cancel{\mathbf{km}}}\mathbf{\times }\frac{\mathbf{1}\mathbf{ }\mathbf{dm}}{{\mathbf{10}}^{\mathbf{-}\mathbf{1}}\mathbf{ }\cancel{\mathbf{m}}}$
