We are required to find the fraction of Earth radius is each type of crust

Average radius of Earth = 6,371 km

Average thickness of oceanic crust = 7.5 km

Average thickness of continental crust = 35 km

fraction of Earth's radius is oceanic crust = 7.5 km / 6,371 km

=

fraction of Earth's radius is continental crust = 35km / 6,731

=

Convert kilometer to mile
