✔ 最佳答案

16 bags<--------------->3.2 kg
7 bags<-------------->(7/16) x 3.2 kg

7 x 0.2 kg = 1.4 kg = 1,400 g

3.2/16=0.2 kg is the weight of each bag.
7 x 0.2= 1.4 kg is the weight of 7 bags.
1.4 x 1000= 1400 grams

3200g / 16bags = 200g per bag * 7 bags = 1400g

3.2kg *100 = 3200 (convert kilos to grams)

3200g/16 = 200g

200g*7 = 1400g

Total weight is 1400grams for 7 bags

3.2 kg/16 bags
= 1/5 kg/bag (0.2 kg/bag)

7 bags * 1/5 kg/bag
= 7/5 kg
= 7/5 kg x 1000 g
= 7000/5 g
= 1400 g

3.2/16=0.2kg per bag
0.2x7=1.4kg
convert to grams
1.4x1000=1400
