Maggie's home computer downloads a

7 megabyte program in 5/6 minute.

Brooke's home computer takes 1 1/4 minutes

to download a 9 megabyte program.

Whose computer downloads at a greater

rate of megabytes per minute?

In this question, Maggie's home computer has greater download rate of megabytes in each minute.

Explanation:

Maggie's home computer downloads 7-megabyte program in 5/6 minute

=> In each minute, it can download a program with: 7 / 5 x 6 = 8.4 megabytes

Similarity, Brooke's home computer downloads 9-megabyte program in 1 1/4 minute (1 1/4 minute = 5/4 minute)

=> In each minute, it can download a program with: 9/5 x 4 = 7.2 megabytes

As 8.4 > 7.2

So that Maggie's home computer has greater download rate of megabytes in each minute.
