Answer 1

a)

1 dm = 100 mm

5 dm 8 mm = 5,08 dm

6 dm 96 mm = 6,96 dm

5 dm 8 mm + 6 dm 96 mm = 5,08 dm + 6,96 dm = 12,04 dm

  5,08

+ 6,96

----------

 12,04  

b)

1 t = 1000 kg

7 t 45 kg = 7,045 t

3 t 289 kg = 3,289 t

7 t 45 kg - 3 t 289 kg = 7,045 t - 3,289 t = 3,756 t

    7,045

-   3,289

---------------

    3,756
