Any number that can be expressed as a fraction is rational such as:-
3 = 3/1, 1.25 = 5/4, 0.125 = 1/8, 0.75 = 3/4 .... etc
Pi.
0.259, 0.25734, 0.0003 are some examples.
2, 3.67, -4.585858.. (repeating) are some examples.
0.269, 0.2734, 0.2790003 are some examples.
7, 2.63, 12/17, 50000006
Some rational numbers are whole numbers, some are not. The set of whole numbers is a proper subset of rational numbers.
No. Rational numbers are numbers that can be written as a fraction. All rational numbers are real.
soem rational numbers are whole numbers
There are an infinite number of rational numbers between 0.26 and 0.29 - some examples are, 0.27, 0.275, 0.28, 0.285
All rational numbers are real so the phrase "real rational" has no meaning. There are an infinite number of subsets: The emply or null set, {1,1.5, 7/3}, {2}, (0.1,0.2,0.3,0.66..., 5.142857142857...} are some examples.
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 real are rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
