Question

Represent the following rational number on the number line.
 $ 1.3 $

Answer 1

Hint: To express a given number on a number line. We first see what is a number and what is its decimal part. A number will tell the exact position or in between which two numbers given a number will lie and the decimal part tells the exact position between those two numbers. Then marking its position on the number line will require expression of the problem.

Complete step-by-step answer:
Given number is $ 1.3 $ `
Clearly we see that the given number is greater than one but less than two.
Therefore, it will lie on the right side of number one but left side of number two on the number line.
For this we first draw a number line and also divide two consecutive numbers in ten equal parts. Which is shown below:

As, given number $ 1.3 $ three its position will be at right of one as it is more by $ 0.3 $ or $ \dfrac{3}{{10}} $ than one.
Therefore, its position will be three parts right of one but left of two and given as or shown as on the number line.

Which is the required expression of $ 1.3 $ on the number line.

Note: To locate any number of a number line. We first see that the given number is in decimal form or in fraction form. If it is in fraction form then we will convert in in decimal form as in decimal form, with the help of a number we can easily locate its position between two numbers on the number line and then using the decimal part we can find or locate exact position of the given number on the number line between two numbers.
