Teacher: Would you rather have one half of an orange or five tenths?

　　Gerald: I‘d much rather have the half.

　　Teacher: Think carefully, and tell me why.

　　Gerald: Because you lose too much juice when you cut the orange into five tenths.

　　杰拉得：我宁可要半个。

　　老师：仔细想想，说出理由来。

　　杰拉得：因为你如果把柑橘切成十分之五，那柑橘汁就损失太多了。
