Question

Which number line correctly shows 4.5 – 2.5?

Answer 1

I say the third one because the end-points start where they are supposed to start/ end.

Answer 2

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$4.5-2.5$

According to the number line,

First we go 4.5 units towards the positive axis of x from the origin.

And then back by 2.5 units from there towards the negative axis of x to show the subtraction.

So, it will interpretate the subtraction of 2.5 from 4.5.

Numerically, it is expressed as

4.5-2.5=2

So, It should reach at 2 in the positive axis of x.

Hence, First option is correct.
