Answer:

79.45 is a rational number, but not a whole number.

Explanation:

A rational number is obtained by dividing one integer by another one to get an integer result. For example, 2/3 equals the rational 78/100 or 842-32=814 that are both integers, which means that they are both valid representation of it. Non-integers are called irrational numbers. Irrationals are also obtained through division sometimes but they do not always end up being an integer at the end even though they still have a finite decimal value for their denominator or numerator (i). Euler's Constant, for instance has the decimal expansion 2.719926... repeated indefinitely and so cannot be represented as an integral.
