Odpowiedź:
1 dag = 10 g
7 dag + 5 g = 75 g
7 * 10g + 5 g = 70 g + 5 g = 75 g
20 dag + 50 g = 250 g
20 * 10g + 50 g = 200 g + 50 g = 250g
10 dag + 8g = 108 g
10 * 10g + 8 g = 100 g + 8 g = 108 g
1 dag + 2 g = 12 g
10 g + 2 g = 12 g
1 dag + 20 g = 30 g
10 g + 20 g = 30 g
10 dag + 80 g = 180 g
10 * 10 g + 80 g = 100 g + 80 g = 180 g
