Explanation:
The value of b must be the same in both comparisons
a : b = 3 : 8 = (3 × 3) : (8 × 3) = 9 : 24
b : c = 6 : 11 = (6 × 4) : (11 × 4) = 24 : 44
The comparisons :
a : b : c = 9 : 24 : 44
The value of :
a + b + c = 9 + 24 + 44 = 77
So, the smallest possible value of a + b + c is 77
Hope it helpful and useful :)
