Answer 2

Fran has the greatest ratio of presentations to reports.

Explanation:

From your description follows:

Fran:

• the height of Reports bar is 2;
• the height of Presentations bar is 9;
• thus, the ratio of Presentations to reports is
  `9:2=4.5:1.`

Lou:

• the height of Reports bar is 4;
• the height of Presentations bar is 3;
• thus, the ratio of Presentations to reports is
  `3:4=0.75:1.`

Tammy:

• the height of Reports bar is 5;
• the height of Presentations bar is 11;
• thus, the ratio of Presentations to reports is
  `11:5=2.2:1.`

Marc:

• the height of Reports bar is 7;
• the height of Presentations bar is 1
• thus, the ratio of Presentations to reports is
  `1:7=(1)/(7):1.`

Shannon:

• the height of Reports bar is 10;
• the height of Presentations bar is 2;
• thus, the ratio of Presentations to reports is
  `2:10=0.2:1.`

Fran has the greatest ratio of presentations to reports.
