Question

write the rational numbers which are shown in the following figure [number line]

explain it ​

Answer 1

Answer:

In order to represent rational numbers on the number line, first we need to draw a straight line and mark a point O on it to represent the rational number zero. The positive (+ve) rational numbers will be represented by points on the number line lying to the right side of O and negative (-ve) rational numbers.

Answer 2

Answer:

P = - 1  

R = -2  

Q= 2  

S=  = 1.75  

Step-by-step explanation:  

It is shown that 4 units mean 1  

so 1 unit means 1/4  

So , P = - 1 since it is left 4 units from 0  

R = -2 since it is 8 units left from 0  

Q= 2 since it is 10 units away from 0 and 2 units right to 2  

S=  = 1.75 Since it is 7 units right to 0 and 1 unit left from 2
