Q2: Write four more rational numbers in each of the following patterns:
(i) (ii)
(iii) (iv)
Answer:
(i)
It can be observed that the numerator is a multiple of 3 while the denominator is a multiple of 5 and as we increase them further, these multiples are increasing. Therefore, the next four rational numbers in this pattern are
(ii)
The next four rational numbers in this pattern are
(iii)
The next four rational numbers in this pattern are
(iv)
The next four rational numbers in this pattern are
Q3: Give four rational numbers equivalent to:
(i) (ii) (iii)
Answer :
(i)
Four rational numbers are
(ii)
Four rational numbers are

Four rational numbers are
Q4: Draw the number line and represent the following rational numbers on it:
(i) (ii)
(iii) (iv)
Answer:
(i)
This fraction represents 3 parts out of 4 equal parts. Therefore, each space between two integers on number line must be divided into 4 equal parts.
can be represented as
(ii)
This fraction represents 5 parts out of 8 equal parts. Negative sign represents that it is on the negative side of number line. Therefore, each space between two integers on number line must be divided into 8 equal parts.
can be represented as
(iii)
This fraction represents 1 full part and 3 parts out of 4 equal parts. Negative sign represents that it is on the negative side of number line. Therefore, each space between two integers on number line must be divided into 4 equal parts.
can be represented as
(iv)
This fraction represents 7 parts out of 8 equal parts. Therefore, each space between two integers on number line must be divided into 8 equal parts.
can be represented as
Q5: The points P, Q, R, S, T, U, A and B on the number line are such that,
TR = RS = SU and AP = PQ = QB. Name the rational numbers represented by P, Q, R and S.
Answer:
Distance between U and T = 1 unit
It is divided into 3 equal parts.
TR = RS = SU =
R =
S =
Similarly, AB = 1 unit
It is divided into 3 equal parts.
P =
Q =
