1. 1 1/6 + 2.2 - 55% = 7/6 + 22/10 + 55/100 = 7/6 + 11/5 + 11/20 = 140/120 + 264/120 + 66/120 = 470/120 = 47/12
2. 35% + 1 1/5 - 0.8 = 35/100 + 6/5 - 8/10 = 7/20 + 6/5 - 4/5 = 7/20 + 24/20 - 16/20 = 15/20 = 3/4
3. 2 1/2 - 0.57 - 65% = 2.5 - 0.57 - 0.65 = 1.28
4. 5 3/4 - 2.5 + 24% = 5.75 - 2.5 + 0.24 = 3.49
5. 4.85 - 65% + 7/10 = 4.85 - 0.65 + 0.7 = 4.9
