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
35 new teachers. An increase from 95 teachers to 130 teachers would reduce the ratio to 19:1.
Answer172 students are in the school. AnswerYou can't really say 172 exactly. Maybe some students are indifferent to it. AnswerThere are "at least" 172 students are in the school.
The school saw a decrease in students of 18.3801%
its all about the size of the school, as in, how many students the school has
3A or 4A schools are about the size of the students. 4A schools have more students than a 3AM school
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?

18 * 35 = 630 total students 630 / 30 = 21 total classes An additional 3 classes.
3 classes
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.
