Q12: State True or False:
(a) In 3/7, 3 is the part of whole.
(b) On a number line, 2/7 is to the right of zero.
(c) 2/5 is smaller than 1/5.
(d) 28/45 and 3/5 represent equivalent fractions.
Ans: (a) True
In the fraction, 3/7, numerator is 3 and denominator is 7, which means that a unit has been divided into 7 equal parts out of which 3 parts have been taken into account.
(b) True
All positive fractions are greater than zero and lies to the right of zero.
(c) False
When denominators are same in two fractions, the fraction with the greater numerator is greater than the other fraction.
Here, in the fractions 25 and 15, denominators are same and in the numerators 2 and 1, 2 is greater than 1.
So, 25 > 15
(d) False
In the fractions, 28/45 and 35 comparing their cross products,
28 × 5 = 140 and 45 × 3 = 135, we observe that they are not equal.
Hence, 28/45 and 3/5 are not equivalent fractions.

Q13: Match the following:
Ans: (a) → (iv)
4 parts are shaded out of 5 parts.

(c) → (ii)
3 parts are shaded out of 6 parts.
Therefore, the shaded portion
(d) → (iii)
1 part is shaded out of 3 parts.
Therefore, the shaded portion = 1/3
