Exercise 4B
Page-66Question 1:
Represent each of the following rational numbers on the number line:
(i)
(ii)
(iii)
(iv)
(v)
(vi)
(vii)
(viii)
(ix)
(x)
Answer 1:
(i)
(ii)
(iii) (7/3)=2+(1/3)
(iv)
can be written as . So, we need to move to the right of point 3. Then, we need to move distance more to the right.
(v) can be written as 4+. So, we need to move to the right of point 4. Then, we need to move distance more to the right.
(vi)
(vii)
(viii)
can be written as . So, we need to move to the left of point -1. Then, we need to move distance more to the left.
(ix)
can be written as . So, we need to move to the left of point -7. Then, we need to move distance more to the left.
(x) can be written as . So, we need to move to the left of point -4. Then, we need to move distance more to the left.
