You can first set up a ratio to see how many TOTAL computers are needed for a r to 12 ratio.
(5/12) = (x/924) Now cross multiply to solve. 12x = 5(924) 12x = 4620
Divide both sides by 12. x = 385
There are a total of 385 computers needed for the school to have a 5:12 ratio.
Since the school already has 125 computers subtract 385-125 = 260. They need to purchase 260 more computers.

Answer:
260 computers will be required more for 125 students.
Step-by-step explanation:
As it is given in the question school wants to have 5 computer for every 12 students.
Current number of computers are 125 and number of students are 924.
Let the number of computers is n for 924 students and the ratio of computers and students is 5 : 12
So [tex]\frac{\text{Current number of computers}}{\text{Current number of students}}[/tex]=[tex]\frac{5}{12}[/tex]
Therefore, [tex]\frac{x}{924}=\frac{5}{12}[/tex]
x = [tex]\frac{924\times 5}{12}=385[/tex]
But the number computers is = 125
Therefore, number of computers required more will be
385 - 125 = 260
260 computers will be required more for 125 students.
