Answer: Option d.
Step-by-step explanation:
We know that:
- Integers contains positive numbers, negative numbers and zero.
- A rational number is that number that can be written in the following form:
[tex]\frac{a}{b}[/tex]
Where "a" and "b" are integers ([tex]b\neq 0[/tex]).
- A Whole number is any of the numbers {[tex]0, 1, 2, 3...[/tex]}
Given the number set:
{[tex]3, 12, 35, 56[/tex]}
These numbers are Rational numbers, because:
[tex]3=\frac{3}{1}\\\\12=\frac{12}{1}\\\\35=\frac{35}{1} \\\\56=\frac{56}{1}[/tex]
And, since they are positive, they are Whole numbers and Integers.
