Answer 1

1/6 + 3/4= (2+9)/12=11/12
2/21+3/14=(4+9)/42=13/42
7/15+3/20=(28+9)/60=37/60
8/9 +5/36=(32+5)/36=37/36
1/7+5/9= (9+35)/63=44/63
5/12+7/18= (15+14)/36=29/36
3/25+17/30= (18+85)/150=103/150
8/11+2/33= (24+2)/33=26/33
5/18+7/24= (20+21)/72=41/72
9/32+5/8= (9+20)/32=29/32
23/81 + 4/27= (23+12)/81=35/81
16/93+12/31=(16+36)/93=52/93
