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
a school has 18 classes,with 35 students in each class.in order to reduce the class size to 30, how many new classes will be formed?
a)2
b)3
c)5
D)6
e)8
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.
To calculate the number of new classes that must be formed in order to reduce the class size to 30, you can follow these steps:
1. Start by finding the total number of students in the current setup: 18 classes * 35 students/class = 630 students.
2. Determine the number of classes needed to accommodate the desired class size of 30 students. Divide the total number of students (630) by the desired class size (30): 630 students / 30 students/class = 21 classes.
3. Finally, subtract the current number of classes (18) from the required number of classes (21): 21 classes - 18 classes = 3 new classes.
Therefore, you would need to form 3 new classes in order to reduce the class size to 30 students.
