Answer» Let the three parts be A, B, C. Then, A : B = 2 : 3 and B : C = 5 : 8 = 5 * 3/5 : 8 * 3/5 = 3 : 24/5 => A : B : C = 2 : 3 : 24/5 = 10 : 15 : 24 Let the three parts be A, B, C. Then, A : B = 2 : 3 and B : C = 5 : 8 = 5 * 3/5 : 8 * 3/5 = 3 : 24/5 => A : B : C = 2 : 3 : 24/5 = 10 : 15 : 24 => B = 98 x 15/49 = 30. |
