Answer:
The answer to your questions is: 25 new teachers
Step-by-step explanation:
Data
# of students = 2000
ratio = 3:80 teachers to students
New teachers = ?
Process
I suggest to use rule of three to solve this problem
3 teachers ---------------- 80 students
x ---------------- 2000 students
x = (2000 x 3) / 80 = 75 teachers
Number of initial teachers = 75
The ratio change to 1:20
1 teacher ------------------- 20 students
x ------------------- 2000 students
x = (2000 x 1) / 20
x = 100 teachers
Number of new teachers = 100 - 75 = 25
Your answer to this problem is 15
10 + 2 - 15 / 3 = 7

Answer:
We have, 48% × x = 12
or,
48
100
× x = 12
Multiplying both sides by 100 and dividing both sides by 48,
we have x = 12 ×
100
48
x = 25
If you are using a calculator, simply enter 12×100÷48, which will give you the answer.
