Find:
(a) 1/2 of (i) 24 (ii) 46
(b) 2/3 of (i) 18 ii) 27
(c) 3/4 of (i) 16 (ii) 36
(d) 4/5 of (i) 20 (ii) 35

Solution:

A fraction is equal parts of a whole thing where numerator represents the number of equal parts and denominator represents equal parts of the whole thing.

We will multiply numerator with numerator and denominator with denominator.

(a) (i) 1/2 of 24 = 1/2 × 24 = 12
(ii) 1/2 of 46 = 1/2 × 46 = 23

(b) (i) 2/3 of 18 = 2/3 × 18 = (2 × 18)/3 = 36/3 = 12
(ii) 2/3 of 27 = 2/3 × 27 = 2 × 9 = 18

(c) (i) 3/4 of 16 = 3/4 × 16 = 3 × 4 = 12
(ii) 3/4 of 36 = 3/4 × 36 = 3 × 9 = 27

(d) (i) 4/5 of 20 = 4/5 × 20 = 4 × 4 = 16
(ii) 4/5 of 35 = 4/5 × 35 = 4 × 7 = 28
