# Question: Jets Fans in a Dormitory

## Comment on Jets Fans in a Dormitory

### How did you get 5/12

How did you get 5/12

### Good question.

Good question.

When we add the given fractions we get 7/12

So, up to that point, have have only accounted for 7/12 of the students. Since 7/12 + 5/12 = 12/12 = 1, we can conclude that, if 7/12 of the students are accounted for, then 5/12 of the students are NOT accounted for.

Does that help?

### Hi,

Hi,

I am yet not able to understand how you got 5/12.

Is there an other explaination?

### When we add 1/3 + 1/6 + 1/12,

When we add 1/3 + 1/6 + 1/12, we are determining the proportion of students who are Jets fans, Bears fans or Raiders fans.

1/3 + 1/6 + 1/12 = 7/12
So, 7/12 of the students are Jets fans, Bears fans or Raiders fans
In other words, 7/12 of the students are NOT Dolphins fans.
This means the REMAINING 5/12 of the students ARE Dolphins fans.

Does that help?

### Hi Brent, I got the answer in

Hi Brent, I got the answer in a different way, please let me know if this approach is ok to use for future questions.

5/12=30 thus 10/12=60 thus 1/12=6 thus 10/12+1/6+1/6=12/12=72

### Ahhhh! Very nice reasoning,

Ahhhh! Very nice reasoning, Luis!!

Just to be clear (for others reading this), Luis is saying that, if 5/12 of T = 30, then we can say that 10/12 of T = 60, which means 1/12 of T = 6.
Finally, if 1/12 of T = 6, then 12/12 of T = 72. In other words, T = 72.
