Question

Your school wants to have 5 computers for every 12 students.There are now 125 computers and 924 students.How many more computers are needed to have a ratio of 5 to 12?
Thanks for your help

Answer 1

First, determine the number of computers that are needed for 924 students.

    n =  (924 students)(5 computers / 12 students)
                 n = 385 computers

Since, there are only 125 computers, the difference can be calculated.
     
       d = 385 computers - 125 computers
   
                d = 260 computers

Hence, 260 more computers are still needed.
