Answer 1

Answer:

Fran has the greatest ratio of presentations to reports.

Step-by-step 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 $1:7=\frac{1}{7}:1.$

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.
