18 classes with 35 students each equals 630 children total.
If you put them in classes of 30, you would need to form 21 classes.
A school has 18 classes with 35 students in each class. In order to reduce class size to 30, how many new classes must be formed?
A school has 18 classes with 35 students in each class. In order to reduce class size to 30, how many new classes must be formed?
You reduce each class by 5 (existing - new), and you have 18 classes (given).Multiplying, you have 90 extra students. To put them in classes of 30, divide.90 / 30 = 3 new classes.Three more classes because 18*35 = 630 and 630/30 = 21
You would first multiply 35 x 18 to find out how many total students there are, which is 630. Then, you would divide 630/30, since you can only have 30 students maximum in a class. This gives you the answer of 21 classes must be formed.
There is an excess of 18 x 5 ie 90 so there has to be an extra 3 classes.

It depends on who your students are - you'd have to compare methods with your classes and see which ones each class actually likes.
Noun-verb analysis is a means of identifying classes and their methods. If you look in the "problem statement" (a statement that explains what a software application should do) for nouns, they will often wind up as classes. If you look for verbs, they will be methods of those classes. A simple example of a problem statement might be: We are a training facility. We need to be able to track the classes that students take. Classes are taught by teachers. Students enroll in classes. Each class is assigned to one teacher and one classroom. So, we have classes, students, teachers and classrooms. Class will have methods like AssignTeacher and AssignClassroom. Students will have Enroll. Of course, there is more, such as how to handle the time of each class, and so on. But this gives an idea.
There are several factors in placing students in classes. Teachers sit down with the names of the incoming students for the new school year. They do this at the end of the school year each spring. The teachers are given test scores, grades, behavior, special needs, and requested students. The requested students go to the teachers that have been asked for. Then, the teachers discuss each student and where they think who would be the best teacher for them. The classes are also put together to have an equal number of boys and girls, the same class size, and a equal number of children with behavior/ learning problems. This is how classes are put together. It takes several days to do and at times students may be moved for one reason or another.
I'f you miss a class you will have to do twice your work.
