If you try to divide 1/1 by 1/2 with this method, you will get 1/0 (because 1/2 = 0), which is definitely not the correct result In Maths, rational numbers are represented in p/q form where q is not equal to zero. It is also a type of real number. Any fraction with non-zero denominators is a rational number. Hence, we can say that '0' is also a rational number, as we can represent it in many forms such as 0/1, 0/2, 0/3, etc That is the formal definition of a rational number. That is how we can make any number of arithmetic look. An integer itself can be written as a fraction: 5 = .And from arithmetic, we know that we can write a decimal as a fraction.. When a and b are natural numbers, then we can always name the ratio that the fraction has to 1, which is the same as the numerator has to the denominator

Numbers like sqrt2, sqrtx (where x is a positive rational number but not the square of a rational number), pi etc. cannot be expressed as ratio of two integers like rational numbers, but can be represented on real number line. These numbers are called irrational numbers. Hence, though all rational numbers are real numbers, there are some. Formally, rational numbers are the set of all real numbers that can be written as a ratio of integers with nonzero denominator. Rational numbers are indicated by the symbol . Note: Real numbers that aren't rational are called irrational. See als

Now what about 22 over seven. Well, here it's clearly represented, already, as a fraction of two integers, but I don't think I can represent this any other, except as a fraction of two integers

A real number is a number that can take any value on the number line. They can be any of the rational and irrational numbers. Rational number is a number that can be expressed in the form of a fraction but with a non-zero denominator. Rational numbers are a subset of the real numbers Rational numbers are those numbers that can be expressed as a fraction, thus producing a ratio between two numbers. Any number that cannot be expressed as a fraction is considered irrational The Unicode numeric entity codes can be expressed as either decimal numbers or hexadecimal numbers.

Rational and Irrational numbers both are real numbers but different with respect to their properties. A rational number is the one which can be represented in the form of P/Q where P and Q are integers and Q ≠ 0.

The number 3/2 is a rational number because it is expressed as a fraction in simplest form. Consequently, the rational number 6/4 is also equal to 3/2, because 6/4 can be simplified to 3/2 As you are aware, there are commands to put a bar or a tilde over a symbol in math mode in LaTeX.

Edmund Landau (1877-1938) denoted the set of integers by a fraktur Z with a bar over it in Grundlagen der Analysis (1930, p. 64).
