1. Verminder die volgende massa met 50 g:

1.1 2 916 kg = ________________________________ kg

1.2 2,048 kg = ________________________________ kg

1.3 0,800 kg = ________________________________ kg

1.4 26,132 kg = _______________________________ kg

2. Vermeerder die volgende massa met 300 g:

2.1 2,798 kg = ________________________________ kg

2.2 3,804 kg = ________________________________ kg

2.3 0,919 kg = ________________________________ kg

2.4 18,497 kg = _______________________________ kg

3. Bereken ook die volgende sonder ‘n sakrekenaar. (Wenk: maak eers die eenhede dieselfde.)
