В сантиметрах:

1 см = 10 мм

9 мм = 9 : 10 = 0,9 см

29 мм = 29 : 10 = 2,9 см

31 мм = 31 : 10 = 3,1 см

256 мм = 256 : 10 = 25,6 см

491 мм = 491 : 10 = 49,1 см

12 см 3 мм = 12 + 3 : 10 = 12 + 0,3 = 12,3 см

8 см 5 мм = 8 + 5 : 10 = 8 + 0,5 = 8,5 см

В центнерах:

1 ц = 100 кг

3 ц 24 кг = 3 + 24 : 100 = 3 + 0,24 = 3,24 ц

11 ц 8 кг = 11 + 8 : 100 = 11 + 0,08 = 11,08 ц

5 ц 24 кг = 5 + 24 : 100 = 5 + 0,24 = 5,24 ц

632 кг = 632 : 100 = 6,32 ц

3 750 кг = 3 750 : 100 = 37,5 ц

41 141 кг = 41 141 : 100 = 411,41 ц

В минутах:

1 мин. = 60 с.

2 мин. 33 с. = 2 + 33 : 60 = 2 + 0,55 = 2,55 мин.

5 мин. 42 с. = 5 + 42 : 60 = 5 + 0,7 = 5,7 мин.

9 мин. 54 с. = 9 + 54 : 60 = 9 + 0,9 = 9,9 мин.
