Answer:

Step-by-step explanation:

Let the 3 numbers be 4x , 5x and 6x

4x + 6x = 5x + 55

10x = 5x + 55                      Subtract 5x from both sides.

<u> 5x     5x</u>

5x = 55                                Divide by 5

x = 55/5

x = 11

Therefore the numbers are

3*11 = 33

4*11 = 44

5*11 = 55
