900个学生,30个学生一个班,得出一共30个班;30个班每个班每天6课时,一天一共180课时;180课时,每个老师教5课时,所以如果同一天的课全都有教师上,至少要要180/5=36个教师一天
900/30=30个班 30*6=180课时 180/5=36个老师可以cover这么多课时
class periods 课时,这道题纯算,不用想一起上之类的。

class period不知道什么意思;900个学生,每个班有6个课时,每个班有30个学生,每个老师教一个class,教5个休一个,900/30=30个班,30*6=180课时,180/5=36个老师。。。
一共900个学生,6个课时,1个老师教1个班,每个班有30名学生,每个老师教5个课时就休息一个课时。那么:900/30=20个班,30*6=180课时,180/5=36个老师
900个学生,6个课时,1个老师教1个班,每个班30个学生,每个老师教5个课时休息1个课时
900/30=30个班
30*6=180课时
180/5=36个老师
