Best Answer

As the students can be split into 2, 3 or 5 groups with no students left over, the number of students in the classroom must be divisible by 2, 3 and 5.

Hint: Find a number which is a multiple of 2, 3 and 5.

The easiest way to find a multiple of any numbers is to just multiply them together:

2 x 3 x 5 = 30.

Other possible multiples of 2, 3 and 5 would include all multiples of this, namely 60, 90, 120, etc.

As it would be a classroom containing students, the most likely number would be the smallest multiple, namely 30.

Unpacking the maths behind this question, it is effectively asking:

What is the Lowest Common Multiple of 2, 3 and 5?

Which is, for example, an important consideration when adding or subtracting fractions - by using the Lowest common multiple it avoids the number getting too big and difficult to manage.

20 x 19 x 18/3 x 2 = 1,140 groups

Our Moon's maria are currently believed to have been formed by ancient volcanic eruptions.

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.

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?

WHY!!!!!!!!!!!!!

In the classroom, first of all,we can see the teacher and the different kinds of students corresponding to the leader and the different kinds of people in the society. Also in the classroom, there is the presider; the teacher, of the different groups formed with officers in each group; like the society, there is the president governing the different groups and communities of people with their own leaders and officers as for example, the governors, mayors, councilors, etc and the members. In the classroom, there are also rules and regulations being followed and should be followed to have harmony among teacher and students as in the society, the are laws, rules and regulations to be and should be followed by the citizens to have a peaceful and progressive community. In the classroom too, we can observe that the students try to cooperate with each other and work faithfully to be effective students and will have higher grades. Whereas in the society, the people cooperate with each other and do work diligently to have a richer and effective community and the members will soon find higher waged work and even be promoted still higher positions. in the classroom we can also observe that some students are working/studying hard as others just normal, without any preoccupations and still others "walang pakialam sa studies or grades nila" like the society, others work hard, others just letting "it " be, following the flow and still others, lazy people, " mga walang pakialam sa buhay. by Anonymous .
