Exercise 1.2

1. Represent these numbers on the number line.

i. 97

Solution:

97 = 127157

So, the number lies on the rightleft of 1.

We can divide the line between 1 and 2 into equal parts.

Thus, 97 represents the secondfifth point from 1.

ii. −75

Solution:

−75 = −125−157

So, the number lies on the leftright of -1.

We can divide the line between -1 and -2 into equal parts.

Thus, −75 represents the thirdsecondfifth point from -2.

2. Represent −213 , 513 , −913 on the number line.

Solution: We can divide the given below line into parts.

Moving from left to right, the order of appearance of the given numbers: , and then
