use a tape diagram

at the fair the ratio of male to females was 3: 9 if there are 360 people at the fair how many males are there
use a tape diagram

1.) Number of Total Shirts = 220

In Figure 1, Red boxes represent "short sleeve shirts" which is 7 in number whereas Blue boxes represent "long sleeve shirts".

1 box contains = 220/10 = 22 shirts 

Number of short sleeves = 22 * 7 = 154

In short, Your Final Answer would be: 154 

2.) Number of Total Subscribers = 260

In Figure 1, Red boxes represent "regular subscribers" which is 10 in number whereas Blue boxes represent "premium subscribers".

1 box contains = 260/13 = 20 subscribers. 

Regular subscribers = 20 * 10 = 200 

In short, Your Final Answer would be: 200

3.) Number of Total People = 360

In Figure 1, Red boxes represent "Males" which is 3 in number whereas Blue boxes represent "females".

1 box contains = 360/12 = 30 people

Number of males: = 30 * 3 = 90

In short, Your Final Answer would be: 90

Hope this helps!
