Answer:

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.
