Answer» (a) 15, 45, 40, 120 15/45 = 1/3; 40/120 = 1/3 Therefore, 15 : 45 = 40 : 120 Hence, these are in proportion (b) 33, 121, 9, 96 24/28 = 6/7, 36/48 = 3/4 Therefore 33 : 121 ≠ 9 : 96 Hence, these are not in proportion (c) 24, 28, 36, 48 33/121 = 3/11, 9/96 = 3/32 Therefore, 24 : 28 ≠ 36 : 48 Hence, these are not in proportion (d) 32, 48, 70, 210 32/48 = 2/3, 70/210 = 1/3 Therefore 32 : 48 ≠ 70 : 210 Hence, these are not in proportion (e) 4, 6, 8, 12 4/6 = 2/3, 8/12 = 2/3 Therefore 4 : 6 = 8 : 12 Hence, these are in proportion (f) 33, 44, 75, 100 33/44 =3/4, 75/100 = 3/4 Therefore, 33 : 44 = 75 : 100 Hence, these are in proportion |
