Georgia [21]

Answer:

Option B, C, and D

Step-by-step explanation:

This is the complete question below;

The ratio of pages read to minutes for Hang is 5 : 8. Who has a greater ratio of pages read to minutes than Hang? Select all that apply. A. Kira:2 pages read every 4 minutes B. Joe:6 pages read every 9 minutes C. Quon:5 pages read every 7 minutes D. Lulu:10 pages read every 13 minutes E.

EXPLANATION:

We are given, The ratio of pages read to minutes for Hang as 5 : 8. Which means 5/8= 0.625, then we can say he read 0.625 of a page per minute.

Let us do this for each of the given options;

A. Kira:2 pages read every 4 minutes

Kira's rate= 2/4= 0.5page per minute.

B. Joe:6 pages read every 9 minute

Then Joe's rate = 0.667page per minute.

C. Quon:5 pages read every 7 minute

Quon's rate = 5/7 = 0.7143page per minute.

D. Lulu:10 pages read every 13 minutes

Lulu's rate= 10/13= 0.76923page per minute.

Those that that has a greater ratio of pages read to minutes than Hang are

Joe(0.667page per minute)

Quon( 0.7143page per minute)

and Lulu (0.76923page per minute.)

Because their rate is higher than HANG(0.625 of a page per minute.)
