Answer:

97, 485, 197

Step-by-step explanation:

Given:

  • First number = a
  • Second number = b
  • Third number = c

Then we have:

  • b = 5a
  • c = 100+a
  • a + b + c = 779

Substituting b and c in the third equation:

  • a + 5a + 100+a = 779
  • 100 + 7a = 779
  • 7a = 779- 100
  • 7a=679
  • a= 679/7
  • a = 97
  • b= 5*97 = 485
  • c = 100+ 97 = 197
