Moreover, these numbers can be positive or negative. Rational numbers happen to be real numbers. Question 3: Give a simple definition of rational number?Īnswer: A rational number refers to a number that one can write as a fraction. Though it can be a natural number and an integer only if the denominator is 1. Question 2: If we divide a positive integer by another positive integer, what is the resulting number?Īnswer : The correct option is “C”. If we divide a positive integer by another positive integer, the resulting number is always a rational number. P = numerator, q= denominator, where p and q are integers and q ≠0Įxamples: \( \frac \) The numerator and the denominator will be integers. Here the denominator should not be equal to 0. But what is a rational number?Ī rational number is a number that can be written in the form of a numerator upon a denominator. So all the numbers that we see collectively on the number line are called integers. Now in these sets, if we also include the negative numbers, then we call it as integers. If we include 0 in these sets of numbers, then these numbers become whole numbers. Natural numbers are the ones that begin with 1 and goes on endlessly up to plus infinity. The numbers that we are familiar with are natural numbers, whole numbers, and integers. We already know about some types of numbers.
