Answer 2

Numbers that can be represented on the number line are called Real Numbers.

Step-by-step explanation:

• Real numbers can be represented by a number line, which is a straight line representing integers at equal intervals. Both positive and negative integers are represented by a number line in a row. This line extends indefinitely at both ends.  
• Number lines refer to real numbers, i.e. natural numbers, integers, rational numbers and proportional numbers, and are used specifically for comparing and sorting numbers.

Steps to represent the Real Numbers on a Number line:

Real numbers can be specified in numerical order with coordinates and graphs. Here are the steps that represent the real number on the number line:

1. Draw a horizontal line with arrows on both ends and mark off the number 0 anywhere. The number O is called the origin.
2. Mark real numbers in equal length on both sides of the origin and label them with a definite scale.
3. Positive numbers lie on the right side of the origin and the negative numbers lie on the left side of the origin.
4. Natural numbers, whole numbers, and integers can be marked easily by locating that particular point on the number line. If the given point is a large number let's say 100, we can change the number line scale accordingly. In this case, we can choose 1 unit as 20, so to mark 100, we just have to take 5 steps towards the right side of the origin.
5. Rational numbers and irrational numbers can be first converted to their decimal equivalents, and then we can mark them on the number line. Sometimes, it is not possible to mark a number on the exact point, so we have to consider the approximate decimal values of the numbers.

For Example, Mark the real numbers - 5/2, 0, 3/2 and 2 on a number line.
