The thinnest layer of the Earth's crust can be found underwater.
The mantle is the thickest layer of the earth.
This depends on whether you treat the core as a single layer or split it into the outer and inner core. The Earth's core has a radius of approximately 3,470 km whereas the Earth's crust is on average only 60 km thick. This as a fraction is 60/3,470 which can be simplified to 1/58. That means that the core is approximately 58 times thicker than the crust. The mantle (which is thickest if you split the core into it's inner and outer components) is 2830 km thick. Thus, as a fraction it is 60/2,830 which simplifies to approximately 1/47.
The fraction is(thickness of the thinnest layer)/(thickness of the thickest layer) After you write that fraction, you can simplify it if you feel like it.

It would be (measure of thickest layer)/(measure of thinnest layer), with both measurements expressed in the same units.

The Earth's crust is thinnest under the oceans and thickest in the mountains.
The Earth's crust is thinnest under the oceans and thickest in the mountains.

60/3,470 i cant show my work
The layer that is thinnest under the oceans is the crust. While it is thinnest in those underwater regions, it is the thickest in the regions where mountains are.
The crust is the thinnest, followed by the outer core, inner core, and the mantle is the thickest.
