三百个人用英语怎么说

"Three hundred people" 用英语说是 "three hundred individuals" 或 "three hundred people"。

来源：这个短语是由两个单词 "three" 和 "hundred" 组成的， "three" 是表示数字3的单词， "hundred" 是表示数字100的单词。

例句：

There were three hundred people at the concert last night. (昨晚演唱会上有三百人。)
Three hundred individuals were surveyed for the study. (研究中调查了三百人。)

Note: 当三百个人被看成一个整体时，我们可以使用" three hundred" 代替" three hundred individuals" 或 "three hundred people"。
