what fraction of the thickness of the thickest continental crust is the thickness of the oceanic crust ? Give your answer as a reduced fraction.
so, you have two numbers.
write them as a fraction.
To determine the fraction of the thickness of the thickest continental crust compared to the thickness of the oceanic crust, we need to gather some information.
First, we need to find the average thickness of the continental crust. This value varies depending on the location but is typically around 30-35 kilometers (30,000-35,000 meters).
Next, we need to determine the average thickness of the oceanic crust. Again, this value can vary, but on average, it is approximately 5-10 kilometers (5,000-10,000 meters).
Now, let's find the fraction by dividing the thickness of the oceanic crust by the thickness of the continental crust:
Fraction = (Thickness of Oceanic Crust) / (Thickness of Continental Crust)
Let's take the average thickness of the oceanic crust as 7 kilometers (or 7,000 meters) and the average thickness of the continental crust as 32 kilometers (or 32,000 meters).
Fraction = 7,000 / 32,000
To reduce this fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD is 1.
Reduced Fraction = 7,000 / 32,000 = 7 / 32
Therefore, the fraction of the thickness of the thickest continental crust compared to the thickness of the oceanic crust is 7/32.
