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
