Hi!
I believe the answer is D , because the common denominator is 12 .
3 times 4=12
4 times 3=12
2 times 6= 12
You multiply each fraction by 12/1 .
Hope it helps and have a wonderful day !

Answer:
1320, permutation
Step-by-step explanation:
There are 12 members
Pick a president
We have 12 choices
Now there are 11 people left to pick from
now pick a vp
We have 11 choices
Now there are 10 people left to pick from
now pick a secretary
We have 10 choices
12*11*10 = 1320
This is a permutation since it matters who is president, vp and secretary
4 * 2 = 8
8 + 5 = 13
B, is the correct answer
