The rational numbers are represented by the numbers that can be expressed as a fraction, where the numerator and denominator are both integers.
Out of the given options, A (-6) and D (7) are integers, so they can be expressed as fractions (e.g. -6/1, 7/1).
Option B (0) can also be expressed as a fraction, 0/1.
However, option C (5.75) cannot be expressed as a fraction with integer numerator and denominator. It is a decimal number, so it belongs to the irrational numbers.
Therefore, the number that belongs only in the rational numbers area of the diagram is C, 5.75.
