Answer:

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

Step-by-step 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.

Just by giving the numbers an analisys, we are able to find the answer, specially because we have options to choose from.

32 is a big part of 48. It's more than half, which would be 24 and would correspond to 50%. Therefore, nor 46 nor 33 can be answers, because 32 is more than the half of 48, so the answer is A.
