Answer:
1. add 20g
2.subtract 550 g
3.subtract 100 g
4.subtract 200 g
Step-by-step explanation:
1. As 1 kg=1000 g so,
980+20=1000 g
2.5 kg =5000 kg so,
5550-550=5000 g
3.We need 750 g so,

Answer:
The completed table is demonstrated in the attached image.
Step-by-step explanation:
i) Quantity to be removed or added
= Weight in Pan 1 - Weight in Pan 2
= 250 - 225
= 25 g
ii) Quantity to be removed or added
= Weight in Pan 1 - Weight in Pan 2
= 1000 - 980
= 20 g
iii) Quantity to be removed or added
= Weight in Pan 1 - Weight in Pan 2
= 5000 - 5550
= -550 g
iv) Quantity to be removed or added
= Weight in Pan 1 - Weight in Pan 2
= 750 - 850
= -100 g
v) Quantity to be removed or added
= Weight in Pan 1 - Weight in Pan 2
= 1000 - 1200
= -200 g
vi) If the answer is positive, then the weight is added. If the answer is negative, then the weight is removed.
