There are no irrational numbers in the value -5.72. All of the components of the value are represented by rational numbers. An irrational number is any number that cannot be represented by a fraction a/b where a and b are integers. -5.72 itself is rational as it can be represented by -572 / 100. The digits of the value are also rational as they can be represented as -5/1, 7/1 and 2/1, respectively.
The mixed fraction is 5 148/625
5 is an integer and not a fraction. It can be represented as a rational fraction (5/1) but not as a decimal fraction.
rational number
Vectors are identified by magnitude, or the length of the line, and direction, represented by the arrowhead pointing toward the terminal point. The position vector has an initial point at (0,0) and is identified by its terminal point ⟨a,b⟩.
There is no point A and so nothing is represented.
It is a mixed fraction.
The fraction is 1.
We would pronounce 0.40 as "Zero point four tenths" and as a fraction would be represented as 4/10.

Eight can be represented as the improper fraction 8/1
rational number
For a fraction A/B, the fraction is improper if A > B. The reciprocal is B/A. So now A is the denominator, and B is the numerator, and B < A, so the reciprocal is a proper fraction. The answer would be always.
Vectors are identified by magnitude, or the length of the line, and direction, represented by the arrowhead pointing toward the terminal point. The position vector has an initial point at (0,0) and is identified by its terminal point ⟨a,b⟩.
k often represents 1000 the multiple, not a fraction.
