What is the difference between rational and whole numbers?

It's like the, ';a square is a rectangle, but a rectangle is not a square'; kind of thing.





A whole number is always a rational number, but a rational number is not always a whole number.





A whole number is any positive number that has no decimals. The name, ';whole'; really helps. Let's think in pies, instead of numbers. If you have a pie and a half, it's not a whole pie. So, it's not a whole number. If you have 3 pies, all three of them are full, they're all whole. So 3 is a whole number. Can you have no (zero) pies? Yes. Can you have negative pies? No.





Rational numbers: any number that can be expressed as a fraction where the numbers are integers. So... root of 2 wouldn't work, and pi wouldn't work (wow... i swear that pun was accidental... =/). Oh, integers are exactly like whole numbers, except it's negatives too. 1/2 works, and so does - 6995838 / 23487293742974927349743. As long as both are integers, it works.





hope i helped :)What is the difference between rational and whole numbers?
whole numbers are a subset of a rational numbers.





whole numbers are 0, 1, 2, 3, 4, 5, ....





rational numbers are fractionsWhat is the difference between rational and whole numbers?
whole numbers 0, 1,2, ..


between 0 and 1 has many rational numbers 1/2, 1/3, 1/4, 2/3, .....
