**Category : **7th Class

We have already studied about the integers, the fractions, the decimals and their operations. We know that for a given integer a and b, their addition, subtraction and multiplication are always an integer but the result of division of an integer by a non-negative integer may or may not be an integer. In this chapter we will study about a new number system which is formed by the division of two integers.

A number which is in the form of \[\frac{a}{b}\] where and b are integers and \[b\ne 0\] is called a rational number, for example \[\frac{-1}{2},\frac{3}{-14},\frac{15}{7}\] are rational numbers.
