1. Introduction to rational numbers

A number that can expressed as \(a / b\), where \(a\) and \(b\) are integers and \(b ≠ 0\) is known as a rational number.

If there are \(10\) apples to be divided for \(4\) children, it is not possible to give \(3\) complete apples to each one. But, if we cut \(2\) apples into half, then there will be \(4\) half pieces and \(8\) full apples. So each child would get \(2\) full and \(1\) half piece of apple.
