Answer:
44, 55, 66
Explanation:
the ratio of the 3 numbers is 4 : 5 : 6 = 4x : 5x : 6x ( x is a multiplier ) , then
6x + 4x ← sum of largest and smallest
5x + 55 ← sum of the third and 55 , then
6x + 4x = 5x + 55
10x = 5x + 55 ( subtract 5x from both sides )
5x = 55 ( divide both sides by 5 )
x = 11
the 3 numbers are then
4x = 4 × 11 = 44
5x = 5 × 11 = 55
6x = 6 × 11 = 66
