Answer 1

4/8+9/24+15/36 =
1/2+3/8+15/36 = 
36/72+27/72+30/72 =
 93/72 = 31/24

7/33+16/44 = 7/33+4/11 = 77/363 + 132/363 = 209/363

9/30+28/20+20/40 = 3/10+14/10+5/10 = 22/10 = 11/5

1/3+20/30+44/33+95/57 = 1/3+4/6+4/3+95/57 = 1/3+2/3+4/3+95/57 = 
19/57+38/57+76/57+95/57 = 228/57 = 4

231/175+231231/175175 = 33/25+33033/25025 = 33033/25025+33033/25025 = 66066/25025
