Ratio
Provided the second integer is not a zero, the ratio will be a rational number.
For elastic, isotropic and homogeneous materials, zero Poisson's ratio means that the material doesn't present lateral deformation on bending, compressing or extending.
Given one ratio, p/q, you will obtain an equivalent ratio if you multiply p and q by any non-zero integer.
It is a rational fraction.
Ratio. It has a true zero.
To address the issue of a zero denominator when converting ratio denominators in After Effects, you can adjust the values of the ratio to ensure that the denominator is not zero. This can be done by either changing the numerator or denominator to a non-zero value, or by using a different ratio altogether that does not result in a zero denominator.
The ratio is not defined.
Ratio
The year is interval scale (no natural zero); your age is ratio.
Provided the second integer is not a zero, the ratio will be a rational number.
After enough years the ratio of survival of everything will turn to zero.
For elastic, isotropic and homogeneous materials, zero Poisson's ratio means that the material doesn't present lateral deformation on bending, compressing or extending.
The neutron has no charge, therefore the charge to mass ratio for the neutron is zero.
72 = 72/1. You can multiply the numerator and denominator of this ratio by any non-zero number to get an equivalent ratio.
It is pretty low, close to zero.
It is a rational fraction.
