We can estimate that v/95 is a little less than 10 by using some simple arithmetic. If we divide any number by a smaller number, the result will be larger than if we divide the same number by a larger number. For example, dividing 10 by 2 gives us 5, while dividing 10 by 5 gives us 2.
In the case of v/95, we know that v is some value that we don't know, and 95 is a fixed value. Since 95 is smaller than 100, we can estimate that v/95 will be slightly larger than v/100. We can also estimate that v/100 is a little less than 10 because if we multiply 10 by 100, we get 1000, which is much larger than any value that v could realistically take.
Therefore, if we assume that v is a reasonable value, we can estimate that v/95 will be slightly larger than v/100, which is a little less than 10. This is a rough estimate, but it gives us a sense of the magnitude of v/95 and suggests that it is likely to be just slightly less than 10.
