a class has 18 classes with 35 students in each class. in order to reduce the class size to 30,how many new classes must be formed?
First we need to find out how many students the class has now.
18 x 35 = ?
Divide that answer by 30 to find how many classes must be formed.
18*35 = x/30
Solve for x

Take the answer you got above and subtract 18 from it to find how many new classes must be formed.
so maythe answer be 3?
Yay! You've got it! :-) The school needs to form 3 new classes.
