Show the following numbers on the number line.
(a) 0.2
(b) 1.9
(c) 1.1
(d) 2.5
To do:
We have to represent the given numbers on the number line.
Solution:
(a) $0.2$ lies between the points 0 and 1 on the number line.
The space between 0 and 1 is divided into 10 equal parts.
This implies,
Each part is equal to $\frac{1}{10}=0.1$.
Therefore,
$0.2$ is the second point to the right of 0.
(b) $1.9$ lies between points 1 and 2 on the number line.
The space between 1 and 2 is divided into 10 equal parts.
This implies,
Each part is equal to $\frac{1}{10}=0.1$.
Therefore,
$1.9$ is the ninth point to the right of 1.
(c) $1.1$ lies between points 1 and 2 on the number line.
The space between 1 and 2 is divided into 10 equal parts.
This implies,
Each part is equal to $\frac{1}{10}=0.1$.
Therefore,
$1.1$ is the first point to the right of 1.
(d) $2.5$ lies between points 2 and 3 on the number line.
The space between 2 and 3 is divided into 10 equal parts.
This implies,
Each part is equal to $\frac{1}{10}=0.1$.
Therefore,
$2.5$ is the fifth point to the right of 2.
