How to Display a Rational Number as a Point on Number line- There are a lot of different types of numbers in mathematics, such as whole numbers, integers, prime numbers, natural numbers, rational, and irrational numbers. Rational numbers are those numbers that can be written in the form of fractions and both numerators and denominators are integers. These numbers can be easily displayed on the number line. There are two types of rational numbers; proper fractions and improper fractions. When plotting the rational numbers on a number line, you need to check whether a fraction is proper or improper. For proper fractions, you need to know that these will always lie between the numbers zero and one. The denominator tells you the number of divisions you need to mark between zero and one. The denominator tells the divisions with reference to zero. When you have to plot an improper fraction on the number line, you have to convert the improper fraction into a mixed number in the form of Quotient (Remainder/Dividend). When plotting, you need to remember that these fractions will always lie between Quotient and Quotient +1. The fraction part of the mixed number can then be marked just like a proper fraction, but it will not lie between 0 and 1.

- Practice 1 - When we open the bracket we get (- , -). Two negative cancel one another out and leave us positive.
- Practice 2 - What is the end value of: –(+25)?
- Practice 3 - If the missing number is smaller than 0, then subtract 1 from the next number. If the missing number is greater than 0, then add 1 to the previous number to the missing number.
