It is rational. Any integer is a rational number, since it can be written in the form (integer)/1.Negative 101 can be written as (-101)/(1) , (101)/(-1) , (-303)/(3) , (78,163)/(-763) ,or an infinite number of other ratios of integers.
The square root of any negative number is not even a 'real' number. It's called 'imaginary', because there's no number you can multiply by itself to get a negative number. The square root of 101 is irrational.
Infinitely many. In fact, between any two different real numbers, there are infinitely many rational numbers, and infinitely many irrational numbers. (More precisely, beth-zero rational numbers, and beth-one irrational numbers - that is, there are more irrational numbers than rational numbers in any such interval.)
