the rational numbers
are the numbers of arithmetic: The whole numbers, fractions, mixed numbers, and decimals; together with their negative images.
1, −6, 3½, -2/3, 0, 5.8, 3.1415926535897932384626433 (an approximation to
pi)
the irrational numbers
there is no whole number, no fraction, and no decimal whose square is 2, 5, 6, 7, 8.....; so, they are the irrational numbers
sqrt%281%29=+1..... Rational
sqrt%282%29.......Irrational
sqrt%283%29.......Irrational
sqrt%284%29=+2......... Rational
sqrt%285%29......., sqrt%286%29......., sqrt%287%29......., sqrt%288%29.......Irrational
sqrt%289%29=3....... Rational
which of them are rational or irrational.
3%2A3.142, .........rational (it is 3%2Api)
2%2F3.142.........rational
sqrt%283%29.......Irrational
sqrt%2816-9%29+=+sqrt%287%29.......Irrational
