Answer :
A whole number is any number without a fractional or decimal part. We need to check each option:
1. For option A, [tex]$42.3$[/tex], there is a decimal component (the [tex]$.3$[/tex]). Therefore, it is not a whole number.
2. For option B, [tex]$\frac{1}{10}$[/tex] equals [tex]$0.1$[/tex], which has a decimal part. Thus, it is not a whole number.
3. Option C is [tex]$6830$[/tex]. This number does not have any digits after the decimal point, so it is a whole number.
4. Option D is [tex]$66$[/tex], an integer with no fractional part. Thus, it is a whole number.
5. Option E is [tex]$808$[/tex]. Since it is written without any decimal indication, it is a whole number.
6. Finally, option F is [tex]$717.59$[/tex]. The presence of decimal [tex]$0.59$[/tex] indicates it is not a whole number.
Therefore, the whole numbers among the given options are:
[tex]$$6830, \quad 66, \quad 808.$$[/tex]
