Question

Which gives the correct values for points A, B, C, and D?

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 = $\dfrac{1}{4}$.

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

$A=-2$

D is 1 mark below 0.

$D=-\dfrac{1}{4}$

C is mark below -1.

$C=-1-\dfrac{1}{4}$

$C=-(1+\dfrac{1}{4})$

$C=-1\dfrac{1}{4}$

B is 3 units below -1.

$B=-1-3(\dfrac{1}{4})$

$C=-1-\dfrac{3}{4}$

$B=-(1+\dfrac{3}{4})$

$B=-1\dfrac{3}{4}$

So, $A=-2,B=-1\dfrac{3}{4},C=-1\dfrac{1}{4},D=-\dfrac{1}{4}$

Therefore, the correct option is A.
