✔ 最佳答案
Mum paid $13.40 for 0.2kg of sweets and a bar of chocolate.
The bar of chocolate cost $8. How much did 1 kg of sweets cost?

中文意思:媽媽付了$13.4來買0.2公斤糖和一條朱古力
每條朱古力售$8, 1公斤糖售價多少?

要你求1公斤糖售價,
就要知道糖幾錢,將$13.4減$8朱古力
得知0.2公斤糖售$5.4
1公斤是0.2公斤5倍
所以$5.4*(乘)5=$27

做法:
1 kg of sweets cost
=5($13.4-$8)
=$27

13.4-8=5.4
5.4÷0.2=27
