Answer :

Numbers a, b, c, d are said to be in proportion if (1) Here,

a = 28, b = 16, c = 21, d = 12 On dividing numerator and denominator by 4 gives, Now, On dividing numerator and denominator by 3 gives, From (i) and (ii)  28, 16, 21, 12 are in proportion

2) Here,

a = 12, b = 32, c = 15, d = 35 On dividing numerator and denominator by 4 gives, Now, On dividing numerator and denominator by 5 gives, From (i) and (ii) 12, 32, 15, 35 are not in proportion

(3) Here,

a = 39, b = 26, c = 57, d = 38 On dividing numerator and denominator by 13 gives, Now, On dividing numerator and denominator by 19 gives, From (i) and (ii) 39, 26, 57, 38 are in proportion
