Answer 1

Given:

A number line.

To find:

The correct values for points A, B, C and D.

Solution:

From the given number line is it clear that there are three marks between any two consecutive integers which divide the number line between those integers in 4 equal parts.

It means, one mark =
`(1)/(4)`.

In the number line, point A is at -2. So,

`A=-2`

D is 1 mark below 0.

`D=-(1)/(4)`

C is mark below -1.

`C=-1-(1)/(4)`

`C=-(1+(1)/(4))`

`C=-1(1)/(4)`

B is 3 units below -1.

`B=-1-3((1)/(4))`

`C=-1-(3)/(4)`

`B=-(1+(3)/(4))`

`B=-1(3)/(4)`

So,
`A=-2,B=-1(3)/(4),C=-1(1)/(4),D=-(1)/(4)`

Therefore, the correct option is A.
