- \(5/8+5/6=15/24+20/24=35/24=1\ 11/24\).
- \(3/20-1/50=15/100-2/100=13/100\).
- \(8/51+3/17=8/51+9/51=17/51=1/3\).
- \(1/3-1/6=2/6-1/6=1/6\).
- Преобразуем десятичную дробь: \(0.35-1/20=0.35-0.05=0.3\).
- \(1/15-1/30=2/30-1/30=1/30\).
- \(3/10-2/15=9/30-4/30=5/30=1/6\).
- \(1/6+8/9=3/18+16/18=19/18=1\ 1/18\).
- \(3/5+0.4=0.6+0.4=1\).
- \(23/45+13/30=46/90+39/90=85/90=17/18\).
- \(1/4+0.5=1/4+1/2=3/4\).
- \(3/4+1/6=9/12+2/12=11/12\).
- \(13/14-5/42=39/42-5/42=34/42=17/21\).
- \(1/8-1/16=2/16-1/16=1/16\).
- \(7/12+11/18=21/36+22/36=43/36=1\ 7/36\).
