hope it helps!

Answer 2

Given : 3.9​

To Find : Show 3.9  on number line

Solution:

Numbers with a negative sign are less than zero

Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.

+ sign numbers can be denoted as simply numbers  

On a number line the number increases as we move to the right and decreases as we move to the left.  

Step 1 : Draw a line and mark some points at equal distance on it as shown in the figure below  Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3  and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on

Divide Each  unit  into 10  equal parts and count 9  point on the right side from 3 and mark to represent   3.9   ( or count 1  on left side from 4)
