46/7 = 6 with a remainder of 4 (6*7 = 42). So, there will be 4 students sitting with a teacher. This means that 7 tables are needed. Also 6*7=42 < 46 < 7*7 = 49, so we can say that there will be 7 tables used.

This can be broken down in this way: Only 7 students are allowed at each table. There are a total of 46 students ,therefore, 46 students / 7 students per table = 6 tables with 4 remaining students who have to sit at the extra table with the teacher.
You get 6 tables with 7 students and 1 parent = 8 per table.
Plus 1 more table that has 4 students and the teacher. 7 tables...

6 full tables plus 4 remaining students which will sit in another table.

46/7=6.57 so there is 6 tables full which is 7x6=42 so there is 4 students left over. So there is 7 tables used in all.
