Certainly! Let's analyze each option provided to identify the whole number among them.
1. [tex]$31$[/tex]
- This is already in the form of a whole number.
2. [tex]$31 \%$[/tex]
- A percentage is a part of a whole. Specifically, [tex]\(31 \%\)[/tex] means [tex]\(31\)[/tex] out of [tex]\(100\)[/tex], or [tex]\( \frac{31}{100} \)[/tex], which is equivalent to [tex]\(0.31\)[/tex].
- [tex]\(0.31\)[/tex] is not a whole number.
3. .31
- This is a decimal number and is equivalent to [tex]\( 31 \% \)[/tex].
- [tex]\(0.31\)[/tex] is not a whole number.
4. [tex]$\frac{1}{3}$[/tex]
- This is a fraction.
- When represented as a decimal, [tex]$\frac{1}{3}$[/tex] is approximately [tex]\(0.3333\)[/tex].
- [tex]\(0.3333\)[/tex] is not a whole number.
From the options given:
- [tex]\(31\)[/tex] is the only whole number.
Hence, the whole number among the choices is:
31
