3Rational Numbers
We have gone through the properties of integers and operations on them in the previous chapter. An important thing about set of integers with the addition and multiplication operations is that it is a ring. Each integer does not have a multiplicative inverse, but multiplication cancellation is allowed in integers.
3.1 Informal Introduction of Rational Numbers
We build an approach for the multiplicative inverse of integers. In this approach, we use a food object pizza. For this purpose, we will restrict our discussion to a positive number of pizzas and the number of persons among whom the pizzas are to be distributed. If the number of pizzas is multiple of the number of persons, we can distribute the pizzas such that every ...
