Kulay, there is no such thing as a "step by step answer" here.  You seem to want a "step by step solution."
I must assume that by 4/5 you actually meant (4/5) and that by 2/3 you meant (2/3).  Then your equation becomes:
(4/5)w - 12 = (2/3)w.  
The LCD here is 5*3, or 15, so mult. every term by 15:
12w - 180 = 10w.   
Add 180 to both sides, obtaining 12 w - 180 + 180 = 10w + 180.     
Then 12w = 10w + 180.  Simplifying, 2w = 180.    What is w?

Answer:
Probability of finding girls given that only English students attend the subject =33/59
Step-by-step explanation:
Given that during English lesson, there is no other lesson ongoing. The probability of getting girls in that class only will be equivalent to 33/59 since we expect a total of 59 students out of which 33 will be girls. Similarly, in a Maths class given that only Maths students attend the class, probability of having a girl is 29/61 since out of all students, only 29 prefer Maths and the total class attendance is 61
 
        
             
        
        
        
It would drop by 24 degrees 
3 x 8 = 24
For each hour another long way is simple just do
3 x 4 = 12 now just double it
12 + 12 = 24
