What fraction of the thickness of the thickest continental crust is the thickness of the oceanic crust? Give your answer as a reduced fraction.
What fraction of the thickness of the thickest Continental crust is the thickness of the oceanic crust give your answer as a reduced fraction
5/100 = 1/20
5km/100 is equal to 1/20 because you dived 5km/100km by 5 which gives you 1/20
What thicknesses are you using for these crusts?
Continental crust is 100km
Oceanic crust is 5km

To determine the fraction of the thickness of the thickest continental crust that the oceanic crust represents, we need to gather some information.
The average thickness of the continental crust is about 35 kilometers (35,000 meters), while the average thickness of the oceanic crust is around 7 kilometers (7,000 meters).
To find the fraction, we divide the thickness of the oceanic crust by the thickness of the continental crust:
Fraction = Thickness of oceanic crust / Thickness of continental crust
Fraction = 7000 / 35000
This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 1000 in this case:
Fraction = 7 / 35 = 1 / 5
Therefore, the fraction of the thickness of the thickest continental crust that the oceanic crust represents is 1/5.
