450' + 17.000'' – 4,2°
= (frac{450}{60} {)}^{o} + ( frac{17000}{60 times 60} {)}^{o} - 4. {2}^{o} \ = 7. {5}^{o} + ( frac{17000}{3600} {)}^{o} - 4. {2}^{o} \ = 7. {5}^{o} + (4 frac{2600}{3600} {)}^{o} - 4. {2}^{o} \ = 7. {5}^{o} + (4 frac{26}{36} {)}^{o} - 4. {2}^{o} \ = 3. {3}^{o} + (4 frac{13}{18} {)}^{o} \ = 3 frac{3}{10} + 4 frac{13}{18} \ = 3 frac{27}{90} + 4 frac{65}{90} \ = 7 frac{92}{90} \ = 7 + frac{90}{90} + frac{2}{90} \ = 7 + 1 + frac{2}{90} \ = (8 frac{2}{90} {)}^{o} \ = (8 frac{1}{45} {)}^{o} \ = 8.02{2}^{o}
