Answer 1

1/7+2/7+4/7=7/7=1
1/63+3/63+5/63=9/63=1/7
17/152+49/152+86/152=152/152=1
29/77-13/77-5/77=11/77=1/7
11/4-1/4-3/4-5/4=2/4=1/2
137/371-35/371-49/371-51/371=2/371

Answer 2

1/7 + 2/7 + 4/7 = (1+2+4) / 7 = 7/7 = 1
1/63 + 3/63 + 5/63 = (1+3+5)/63 = 9/63 = 1/7
17/152 + 49/152 + 86/152 = (17+49+86)/152 =  152/152 = 1
29/77 - 13/77 - 5/77 = (29-13-5)/77 = 11/77 = 1/7
11/4 - 1/4 - 3/4 - 5/4 = (11-1-3-5)/4 = 2/4 = 1/2
137/371 -35/371 - 49/371 -51/371 = (137-35-49-51)/371 = 2/371
