A rational number is a number which can be written in the form of \(p/q\) (ratio) where the denominator(q) is not equal to zero. This implies that it can be represented in the form of a fraction. Thus, every rational number has a numerator and a denominator, that is, one integer divided by another integer, where the denominator is not equal to zero.

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.

In number theory, the multiplicative digital root of a natural number in a given number base is found by multiplying the digits of together, then repeating this operation until only a single-digit remains, which is called the multiplicative digital root of . Multiplicative digital roots are the multiplicative equivalent of digital roots

Prime factorization involves finding the prime numbers that when multiplied, return the number being addressed. For example, prime factorization of 120 results in 2 × 2 × 2 × 3 × 5. It can be helpful to use a factor tree when computing the prime factorizations of numbers. Using 120: 120 / \ 2 60 / \ 2 30 ...
