Rozwiążcie mi to 0,45 h = min 190 min = h 270 s = min 3,4 km = dm 67000000 mm = km dam naj

[latex]1 h = 60 min = 3600 s\1 min = frac{1}{60} h\1 s = frac{1}{60} min\1 km = 1000 m = 10 000 dm = 100 000 cm[/latex] [latex]0,45 h = 0,45*60 min = 27 min\\190 min = frac{190}{60}h = 3,1(6) h\\270 s = frac{270}{60} min = 4,5 min\\3,4 km = 3,4*10000 dm = 34 000 dm\\670 000 000 mm = frac{670000000}{1000000} km = 670 km[/latex]
