做左解題先
Mother measures the total weight of five bottles of water.
If the total weight is measured to be 4 kg 100 g,
record the weight of a bottle of water in kg and g respectively.
媽媽在量度5樽水的重量, 如果總重量是4公斤100克
(真係唔知點解水係用kg公斤?? 而唔係mL及Litre公升?)
請紀錄1樽水的重量, 同時分別用單位kg及g作答

Total weights of 5 bottles of water:
4kg 100g=4100g

Therefore, weights of 1 bottle of water:
4100g ÷ 5
=820g

weights of 1 bottle of water in Kg unit:
820g÷1000
=0.82kg

Total weight = 4100g
so the weight of a bottle of water in g = 4100g / 5 = 820g

and the weight of a bottle of water in kg = 0.82kg

4 kg 100 g is equal to 4100 g

weight of a bottle of water
= 4100/5
= 820 g
