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
