determinig the following numbers in proportion- a)8,12,24,36 b)15,20,45,40 Share with your friends Share 0 Manbar Singh answered this Dear Student, We know that 4 non zero quabtities a, b, c and d are in proportion if a : b = c : d.a. 8, 12, 24, 36Now, 8 : 12 = 812 = 23Now, 24 : 36 = 2436 = 23So, 8 : 12 = 24 : 36Hence, 8, 12, 24 and 36 are in proportion.b. 15, 20, 45, 40Now, 15 : 20 = 1520 = 34Now, 45 : 40 = 4540 = 98Since, 15 : 20 ≠ 45 : 40So, 15, 20, 45, 40 are not in proportion.
