Answer: 9 to 4
Step-by-step explanation:
Using the grids you can count them to see what the width is.
The width is 9 units and the height is 4 units so the ration will be 9 to 4
Here you go! You actually said p(8) twice so I thought you meant Q(8). Please if the equations are wrong update me with the right equation
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.
