Whole numbers ARE rational.
The set of rational numbers includes all whole numbers, so SOME rational numbers will also be whole number. But not all rational numbers are whole numbers. So, as a rule, no, rational numbers are not whole numbers.
All whole numbers are rational so there are infinitely many rational numbers that are whole numbers.
Yes, by definition. A rational number is one that can be written as a ratio (hence rational) of two whole numbers. And a ratio of two whole numbers is a fraction.
soem rational numbers are whole numbers
No, they are not. 1/2 is a ratio of two integers and so it is rational. But it is not a whole number.
Some rational numbers are whole numbers, some are not. The set of whole numbers is a proper subset of rational numbers.
Whole numbers are always rational
Some rational numbers are whole numbers [3/1,10/5,0/2,etc.], but all whole numbers are rational numbers.
All rational numbers are not whole numbers, as rational numbers can include fractions.
Another name for 'rational' is "numbers that are equal to the ratio of two whole numbers". Another name for 'irrational' is "numbers that are not equal to the ratio of any two whole numbers".
Short answer - yes, fractions with whole numbers are rational. All whole numbers are rational. All fractions are rational. Rational numbers can be added to always make another rational number.
